A 27-year-old man presents to the urgent care clinic for diarrhea. The O-antigens at the surface of the outer membrane are exposed and can be linked by anti-O antibodies (resulting in a closely padded granular clumping). There is a wave-like motion to their growth in agar due to its high motility. These bacteria hydrolyze lactose to glucose and galactose and subsequently ferment them to lactate . If you really want to try whey, even if you're lactose intolerant, then start with small amounts. stay inside when it is Really Cold. how to identify enterobacter aerogenes and bacillus cereus. Lactose fermentation also occurs in your body if you are lactose-intolerant. And since lactose is fermented by colonic bacteria, it can also cause bloating and flatulence.
