Alcaligenes faecalis

Alcaligenes faecalis is a Gram-negative, rod-shaped obligate aerobe that is commonly found in the environment. It was originally named for its first discovery in feces, but was later found to be much more common in other places as well. Optimum growth occurs at about 37°C with no pigmentation. While opportunistic infections do occur, the bacterium is generally considered non-pathogenic.

A. faecalis has been used for the production of non-standard amino acids. A. faecalis is normally found in soil, water, and environments in association with humans.
