BIONEXGEN Overview Edition 1, December 2011 Developing the Next Generation of Biocatalysts for Industrial Chemical Synthesis A Framework 7 supported project, this first edition of the project newsletter aims to provide an introduction to the project & partners and highlight relevant research and technology developments. and compounds for anti-oxidants, antifreeze and coolants. In 2007 the total global sales of products made by biotechnology processes totalled €48bn and owing to a number of trends and drivers, including price and availability of crude oil, this sector is expected to grow significantly, with some estimations being in excess of €300bn by 2025. Industrial Biotechnology is defined as: ‘The use of biological substances (including plants, algae, marine life, fungi, micro-organisms) for the processing and production of enzymes, chemicals, materials and energy’. It is therefore already an exciting time for Industrial Biotechnology in the chemical industry but, as more target products are identified, further breakthroughs in technology will be required for the full potential to be exploited. The use of Industrial Biotechnology for the production of chemicals offers a range of advantages for consumers and broader society including: BIONEXGEN aims to provide such breakthroughs. A flagship EU collaborative research project, the goal of BIONEXGEN is to develop the next generation of biocatalysts to be used for eco-efficient manufacturing processes in the chemical industry. • Cheaper, more readily available products, in particular pharmaceuticals and cosmetics • Access to natural and / or eco- friendly products • Products with often reduced CO2 footprint and safer manufacturing routes Biotechnology has been used for hundreds of years in the production of bread, cheese and beer and its industrial application to produce e.g. antibiotics and sweeteners has been established since the 1960s. However, recent developments in synthetic biology have allowed a new wave of products to be commercialised and examples of products of Industrial Biotechnology now include: natural flavourings e.g. vanilla, cocoa butter for chocolates, food packaging, steroids and vitamins, cosmetic moisturizers A number of key technology fields were previously identified with industrial input and included amine synthesis, polymers from renewable resources, glycoscience and wider oxidase applications (e.g. fine chemicals). BIONEXGEN will use these industrially identified products and product family leads to develop biocatalysts which can be used routinely in economically viable industrial production. With a total project budget of over €10m, the research objectives for BIONEXGEN include: • The design and optimisation of enzymes to be used in synthetic chemistry • The development of modified microorganisms which are resistant to heat, pressure or low pH, suitable for use in industrial production • The integration of these biotechnological steps into applied chemical processes BIONEXGEN Overview In this issue: BIONEXGEN Overview 01 Introduction to BIONEXGEN 03 Update on BIONEXGEN Project BIONEXGEN Work 04 Early Success in BIONEXGENA nutraceutical now available for testing 05 Industrial Biotechnology in the Press BIONEXGEN Technology Platforms 06 Technology Platforms – Enzyme Immobilisation Meet the BIONEXGEN Researchers 08 Meet the researchers from three of the project participants BIONEXGEN Overview Co-ordinated by The University of Manchester, the BIONEXGEN project consortium consists of 17 partners from 9 European countries: The University of Manchester, United Kingdom The University of Stuttgart, Germany Technical University of Denmark (DTU), Denmark The Institute of Microbiology of the Czech Academy of Sciences (IMIC), Czech Republic University of Groningen, Netherlands CLEA Technologies BV, Netherlands EntreChem SL, Spain University of Oviedo, Spain GALAB Laboratories GmbH, Germany Leibniz Institute of Plant Biochemistry, Germany Austrian Centre of Industrial Biotechnology, (ACIB) Austria Royal Institute of Technology (KTH), Stockholm, Sweden LentiKats a.s, Czech Republic Slovak University of Technology, Slovakia BASF SE, Germany University College London (UCL), United Kingdom Chemistry Innovation Ltd, United Kingdom For more information on the BIONEXGEN project visit: http://bionexgen-fp7.eu/ BIONEXGEN Research is split into 8 multi-disciplinary themes: Product Areas Industrial Amine Synthesis Amines are vital for the industrial synthesis of pharmaceuticals, bulk and speciality chemicals. Renewable Resources in Novel Polymer Chemistry Polymers are by far the largest volume of chemical products on the market with strong market pull for bio-based polymers in many industries e.g. automotive, packaging, construction, cosmetics and detergents. Applications of Enzymes to Glycoscience Enzymatic methods have great synthetic appeal for this traditionally challenging area of chemistry producing molecules which can be used for controlling health and disease and in food and feed. 02 http://bionexgen-fp7.eu Industrial Applications of Oxidases Development of efficient and robust oxidative biocatalysts and the technology for performing selective oxidations that will be valuable for use in the pharmaceutical, fine chemical and food industries. Underpinning Technology Fermentation Science A focus on efficient production strains and high density fermentation techniques which are critical to economic performance. Biocatalyst Supports and Chemocatalysts Integration Application of biocatalyst immobilisation technology to utilise biocatalysts in industrial chemical synthesis. Bioprocess and Chemical Engineering Process engineering research to develop and implement new biocatalytic processes in industry. Economic, Environmental and Life Cycle Analysis Developing a simplified methodology for quick and reliable quantitative assessment. BIONEXGEN Update A kick-off meeting, Biotrans conference and the first BIONEXGEN review meeting, there has been plenty of activity in the first 9 months of the project. The BIONEXGEN project started in February 2011 and from the first kick-off meeting, expectations were high. Attending the meeting in Brussels, Alfredo Aguilar Romanillos1, DG RTD, European Commission said the project was unique, receiving the largest budget of any FP7 projects in the KBBE area to date. BIONEXGEN is expected to have real impact in the field of Industrial Biotechnology with tangible benefits for European SMEs working in the area. The project team have quickly built up excellent working relationships and made substantial progress towards the initial goals. The first 6 month report was submitted to the Commission on time in September and feedback from the Project Officer was very positive with all the initial milestones and deliverables being achieved on time. In early October many of the project researchers attended the Biotrans 2011 Conference in Sicily with presentations provided by BIONEXGEN partners University of Manchester, IMIC, Royal Institute of Technology (KTH), The University of Stuttgart and ACIB. Commenting on the conference Dr Kirk Malone, Project Manager of BIONEXGEN said “The conference provided an ideal backdrop for BIONEXGEN due to the quality and breadth of the science being discussed. It allowed our researchers to network with their contemporaries from across the globe, and gave an international stage to present some of our initial research success. We were also able to have a small BIONEXGEN project meeting due to the number of partners in attendance. Overall it was a hugely successful conference, and the University of Manchester looks forward to hosting the event in 2013 (although we can’t guarantee the Sicilian sun and wine!)” October 2011 saw BASF, Ludwigshafen host the first review meeting for BIONEXGEN. Attended by over 40 researchers representing all 17 project partners the two-day meeting provided time for project updates, technical discussions, and detailed work programme break-out meetings. Ensuring opportunity for the project team to get acquainted, BASF hosted an excellent tour of their Wine Cellar at Ludwigshafen and subsequent dinner. The impressive initial results presented provided plenty of discussion and the energy and momentum created by the meeting will surely carry through to the next meeting. Thanks to Dr Kai Baldenius and Dr Vaidotas Navickas of BASF for such excellent organisation of the meeting. 1 Head of Unit Biotechnology, Directorate Biotechnologies, Agriculture and Food. BIONEXGEN Partner Logos The BIONEXGEN newsletter edition 1 03 BIONEXGEN Work CASE STUDY OF BIONEXGEN SUCCESS Production of Isoquercitrin The BIONEXGEN project has facilitated a new process for the production of Isoquercitrin, a nutraceutical. Avoiding difficult extraction processes, this novel route based on ‘green chemistry’ principles uses an enzyme expressed in yeast. Samples are currently being evaluated within the consortium. Isoquercitrin, a flavonoid naturally occurring in vegetables and fruits, is known to be active against many human health conditions including: cardiovascular disease, asthma, stroke, capillary fragility, arteriosclerosis, trauma, oxidative stress, hypertension, elevated cholesterol, elevated triglycerides, hyperglycemia, type II diabetes, obesity and related disorders, and Alzheimer’s disease. A strong antioxidant and chemoprotectant, isoquercitrin is devoid of the unwanted side effects of quercetin (its aglycon) in addition to having better solubility in water and higher bioavailability. Isoquercitrin therefore has a good potential for application in nutraceuticals, adjuvant therapy of cancer, and in dermatological preparations and is currently being evaluated in research trials. However, despite its relatively high content in e.g. apples, onion (ca 50 - 300 mg/kg) its isolation is technically extremely complicated, resulting in a very high price and thus limiting trials for wider applications. Within the BIONEXGEN project, Professor Kren and his team at Inst. of Microbiology, Prague, CZ (IMIC), have been able to produce high yields of isoquercitrin from rutin, a naturally occurring product available from Brazilian tree fava d’anta (Dimorphandra mollis), 04 http://bionexgen-fp7.eu BIONEXGEN Work using an enzyme sequenced and expressed in yeast. extremely useful for further scaleup, for which experiments are now under way and immobilization into the CLEA system is also under preparation. Both the enzyme (wild or cloned expressed in yeast) and the product (isoquercitrin) are available to all consortium partners for further evaluation. Fig. 1 Rutin (1) derhamnosylation to Isoquercetin (2). Their procedure is based on ‘green chemistry’ principles without any toxic additives. Moreover, it is a “waste-free” procedure since the biotransformation medium can be recycled and used as production medium for the fermentation stage. The biotransformation uses a known enzyme, previously employed to enhance grape juice aroma and wine aromas. The enzyme has been found to exhibit exceptional biochemical properties; thermo- and alkali-tolerant, enabling long-term operation at 70˚C and pH 8.0. This procedure enables very high volumetric productivity (up to 300 g/L) and yields the product devoid of highly unwanted quercetin. Commenting on the work Prof Kren said “The significant advantage of our expression system consists in shorter production times, up to fourfold increase of enzyme yields and the absence of unwanted β-D-glucosidase as compared to the native production system.” The BIONEXGEN project dramatically speeded up the research on this enzyme and allowed scale-up experiments to be done in collaboration with two partners (LentiKats and Slovak Technical University, in Bratislava) recently. Immobilization into the LentiKats system proved to be For more information contact: Prof. Dr. Vladimir Kren Institute of Microbiology, Academy of Sciences of the Czech Republic Laboratory of Biotransformation National Centre of Biocatalysis and Biotransformation Videnska 1083 CZ 142 20 Praha 4, Czech Republic Tel.

BIONEXGEN participants’ selected recent publications: Recent progress in industrial biocatalysis, Bettina M. Nestl, Bernd A. Nebel and Bernhard Hauer, Current Opinion in Chemical Biology, 2011, 15, 187–193 This review describes some of the recent innovative developments in the rapidly growing field of enzymatic catalysis, with particular focus on potential applications in biotransformations. This work describes the combination of molecular biology and bioprocess techniques for the rapid evaluation of multi-step enzymatic syntheses. The approach is illustrated for the asymmetric synthesis of chiral aminoalcohols combining transketolase and transaminase enzymes. Enantioselective Oxidation of C-O and C-N Bonds Using Oxidases, Nicholas J. Turner, Chemical Reviews, 2011, 111, 4073–4087 Oxidation reactions represent a cornerstone of organic chemistry, providing access to a range of functional groups that allow further functionalisation of building blocks used in synthesis. This review focuses on the biocatalytic oxidation of alcohols and amine functional groups. Multienzyme-Catalyzed Processes: Next-Generation Biocatalysis, Paloma A. Santacoloma, Gürkan Sin, Krist V. Gernaey, and John M. Woodley, Organic Process Research & Development, 2011, 15, 203–212 Most biocatalysis studies have been carried out using single enzymes, but multiple enzyme mixtures are attracting more interest for the production of many compounds at an industrial level. In this review, a classification of multienzyme-catalyzed processes is proposed.

Industrial Biotechnology News OECD Report on Future Prospects for Industrial Biotechnology Published in October, this report builds on a number of workshops and reports from 2010/2011 and summaries the potential future for the OECD regions. Concluding that “The outlook is promising: the convergence of industrial biotechnology drivers with the unprecedented progress in the biological sciences is timely. The barriers are many; they must be tackled by regional, national and internationally harmonised policy.” The report can be viewed online here or can be purchased for €33. BASF and Purac to produce biobased succinic acid. BIONEXGEN partners, BASF have announced they plan to enter into a joint venture with CSM subsidiary Purac, to produce bio-based succinic acid. Aiming to be the first commercial producer in the market, they intend to start a 25,000 ton fermentation production plant in Barcelona by 2013. Finding uses as a chemical intermediate, solvent, in polyurethanes, plasticisers and increasingly bioplastics, demand for succinic acid is expected to grow strongly. Read the full announcement here Toyota use 80% bioplastics in new model Toyota has revealed that the interior of the new Sai Hybrid model will consist of 80% materials derived from sugar cane. The bioplastics used will be in exposed surfaces, including seats, trims and carpets. The use of bio-derived monomers in its bio-polyethylene terephthalate (bio-PET) gives materials that perform on cost and properties and they now appear to be replacing the use of fossil derived ethylene glycol. Toyota have been working towards their totally renewable material derived car for a number of years now and this is another step forward. Michelin aims to use bio-isoprene for its tyres. Amyris and Michelin have announced a collaboration to commercialise renewable isoprene in the production of tyres. This follows in the steps of the Goodyear/Genencor agreement announced a few years ago. With Amyris expecting bio-isoprene to be commercialised in 2015, Michelin is committed to taking the material on a ten-year basis. The non-exclusive agreement allows Amyris to provide its renewable isoprene to other customers. Read more here. The BIONEXGEN newsletter edition 1 05 BIONEXGEN Technology Platforms (kgs product per kg enzyme) owing to the large amount of non-catalytic ballast (often > 95% of the total mass). Technology Platforms Enzyme Immobilization • lack of operational stability • lack of storage stability • cumbersome recovery and recycling • product contamination If the use of enzymes as biocatalysts in the production of chemicals is to be fully exploited these obstacles must be overcome. Immobilization of an enzyme by binding to a support, such as an ion exchange resin or silica, or encapsulation in an inert matrix such as a silica sol gel is well known and leads to improved storage and operational stability and provides for its facile separation and re-use. However, these traditional immobilization strategies can be costly and afford carrier-bound enzymes with low productivities 06 http://bionexgen-fp7.eu Cross-linked enzymes, produced by mixing an aqueous solution of the enzyme with an aqueous solution of glutaraldehyde, were already known in the 1960’s and afforded carrier-free immobilized enzymes with high productivities. However, these generally had low activity, poor reproducibility, low stability and shelf life, and were difficult to handle. Consequently, carrier-bound enzymes became the method of choice for the next three decades. In the early 1990s Altus Biologics introduced the use of crosslinked enzyme crystals (CLECs) as industrial biocatalysts. The methodology was applicable to a wide variety of enzymes and CLECs exhibited excellent operational stability, controllable particle size coupled with high productivity and facile recovery and re-use, making them ideally suited to industrial biocatalysis. However, they had one inherent limitation: the need to crystallize the enzyme, a laborious procedure requiring enzyme of high purity which in practice translates to relatively high costs. More recently, ‘smart’ magnetic CLEAs have been prepared by conducting the cross-linking in the presence of functionalized magnetic nanoparticles. These mCLEAs can be separated by magnetic decantation or can be used in a magnetically stabilized fluidized bed potentially leading to novel combinations of bioconversions and downstream processing. A further elaboration of the CLEA methodology is the preparation of combi-CLEAs, from mixtures of two or more enzymes, for use in multi-enzyme cascade processes. CLEA Immobilization Despite recent advancements in the development of biocatalysts, enzymes are complex, highly sensitive molecules with unique three-dimensional structures. When exposed to certain conditions, e.g. elevated temperatures or organic solvents, this structure can be denatured or unfolded resulting in significant activity loss. Other factors affecting the efficiency of enzymes in full-scale chemical production can include: new class of immobilized enzymes called cross-linked enzyme aggregates (CLEA®s). The CLEA methodology essentially combines two unit processes, purification and immobilization, into a single operation. In principle, one can take the crude enzyme extract from fermentation broth and produce the immobilized enzyme in one simple operation. A variation on this theme involves performing the cross-linking in the presence of a monomer that undergoes polymerization under these conditions. This results in the formation of a CLEA-polymer composite with tunable physical properties. For example, if the cross-linking is performed in the presence of a siloxane the latter undergoes polymerization to afford a CLEA-silica composite. The hydrophobic/hydrophilic properties and particle size of the latter can be tailored by manipulating the structure of the siloxane used. Within the BIONEXGEN project two different immobilization technologies will be employed and evaluated, CLEA and LentiKats. In this edition we learn more about the CLEA immobilization technology. Immobilization of enzymes improves storage and operational stability and facilitates recovery and recycling of the biocatalyst. CLEA technology involves crosslinking of the crude enzyme resulting in high productivities. With potential to add functionality e.g. hydrophobicity or magnetic properties this technology has potential benefits for many novel biotransformations. BIONEXGEN Technology Platforms Several years ago, Roger Sheldon and a team of scientists at Delft University of Technology reasoned that crystallization could perhaps be replaced by precipitation of the enzyme from aqueous buffer, a simpler and less expensive method not requiring highly pure enzymes. This led to the development of a Protease-CLEA (free-flowing powder) Benefits of CLEAs CLEAs have many economic and environmental benefits in the context of industrial biocatalysis. They are easily prepared from crude enzyme extracts and the costs of (often expensive) carriers are circumvented. They generally exhibit improved storage and operational stability towards denaturation by heat, organic solvents and autoproteolysis and are stable towards leaching in aqueous media. Furthermore, they have high catalyst productivities (kgs product per kg biocatalyst) and are easy to recover and recycle. CLEAs are highly porous materials and diffusional limitations are generally not observed with standard CLEAs in typical bioconversions. Moreover, the particle size is amenable to tuning with optimum rates being observed with smaller particles but practical considerations, e.g. ease of filtration, often dictating the use of larger particles. Comparison of immobilization techniques The proprietary CLEA methodology has been commercialized by CLEA Technologies and CLEAs from a variety of commercially available enzymes are already for sale on the open market (see www. cleatechnologies.com) as well as custom CLEAs from enzymes provided by clients on an exclusive basis. Work within the BIONEXGEN project will ascertain whether this innovative and cost effective immobilization technology is applicable to the next generation of biocatalysts and subsequent chemistries.
