Production of pepsin by bacteria and fungi from soiland rumen cultured in whey and brans.

摘要

Pepsin producing bacteria and fungi from 10 soil and goat, sheep and cattle rumencontent samples were identified by Biomerieux VITEK 2d and standard methods, and mixedwith pasteurized whey or brans to determine optimal pepsin production. Our results suggestedthat Staphylococcus sciuri and Pythium sp produced optimal clotting at ~15 min at 50C, pH 2.0in 10% whey with 1.0 ml inoculum incubated 24h yielding 4.6 units/ml pepsin.
