Genetics can be altered

• Transformation: DNA from
external environment
• Transduction: virus carries
DNA from one host
bacterium to its next host
• Conjugation: Transfer of
genetic info between 2
bacteria cells via the plasmid
• Food production-Yogurt, buttermilk, sour cream
• Streptococcus sanfranciscus
• Lactobacillus acidophilus
•
• Biofuels, medicine, water purification,
• “Flora”: E. coli- lives in
