Is Ecoli lactose

Answer 1

Lactose is strung together using beta1-4 glycosidic bonds. Some humans cannot digest it (lactose intolerance). In fact, the ability to digest lactose was actually a mutation! When it passes through the digestive tract undigested it empties from the small intestine to the large intestine's cecum. There, gut flora (microorganisms) ferment lactose and other carbohydrates for energy. The fermentation process releases some very helpful compounds for the human's benefit, too (SCFAs).

E Coli is one of the many microorganisms that live in our large intestine. It, and the others, ferment lactose (among other things) for energy.

I hope that answers your question! :)

Answer 2

What on earth do you mean?

"Ecoli" or E. coli (full name Escherichia coli) is a a species of bacteria. Plenty of E. coli live in our gut and are helpful. Some strains (i.e. variants) of E. coli are harmful and can cause food poisoning.

Lactose is the type of sugar found in milk, and in other dairy products to some extent.

If you mean, "Is E. coli lactase positive (Lac+)?", meaning can it ferment lactose for energy, then the answer is yes.

Answer 3

E. coli can ferment lactose into acid and gas. This ability is often tested in laboratories to differentiate between different strains of E. coli.
