WebThe pH of the environment affects bacterial growth. Most bacteria grow best in the pH range from about 6-8; however, there are many acid-tolerant bacteria as well as alkaline-tolerant strains. In general, bacteria survive alkaline pH better than acid pH, but a few strains actually grow better in an acidic environment. http://users.rowan.edu/~jahan/sophclinic/slides/8%20JC%20MicrobialGrowth.ppt
