Enterococcus faecalis contains various small peptides that can promote the absorption of amino acids and residues, and improve the synthesis of tissue proteins. How Enterococcus faecalis works as a feed additive will be delved into in this article.

There are several biological characteristics of Enterococcus faecalis, and many sub-characteristics exist. Furthermore, there are also various instances where Enterococcus faecalis can be identified, many of which are extremely technical, but will be delved into in this article.

Enterococcus faecalis is a Gram positive and hydrogen peroxide negative bacterium.
