Why is lactose fermentation common among enteric gram negative bacteria?

Probably because that is where the gram negative bacteria have found a food source. Lactose is not the perfered diet, but it works and they are most likely there because they can tolerate the environment, and survive (on lactose) when their #1 food source is not available.


Is it true that to use lactose for food e. coli must take lactose across its cell membrane?

Yes, for E. coli to utilize lactose as a food source, it must transport lactose across its cell membrane. This process typically involves specific transport proteins, such as the lactose permease, which facilitate the movement of lactose into the bacterial cell. Once inside, E. coli can metabolize lactose through enzymatic action, primarily using β-galactosidase to break it down into glucose and galactose.

What is transacetylation of lactose?

Transacetylation of lactose refers to a chemical process where an acetyl group is transferred to lactose, typically resulting in the formation of acetylated derivatives of lactose. This reaction can alter the solubility and sweetness of lactose and is often used in food processing and pharmaceuticals to modify the properties of lactose-based products. It can also affect the lactose's digestibility and its interaction with other compounds.
