What different names of bacteria does Vitamin K produce in the intestines?

Answer 1

Your question needs to be rephrased as: "What different names of bacteria in the intestines can produce Vitamin K?"

Vitamin K does not produce bacteria but rather the reverse - bacteria that normally reside in the intestine can synthesize and produce vitamin K (Vitamin K2 or menaquinone).

Escherichia coli found in large intestine plays a major role on that function. Other bacteria found in normal flora of the intestines include: Bacteroides, anaerobic Streptococci, Bifidobacterium, Peptostreptococcus, Clostridium, and many other micro flora which includes over 400 bacterial species.

Answer 2

Vitamin K does not produce bacteria.

Answer 3

Many bacteria, such as Escherichia coli found in the large intestine, can synthesize Vitamin K2 (menaquinone).

Sorry I cannot find all their names, but lots of them do it.
