Enumeration and isolation of cellulolytic and hemicellulolytic bacteria from human feces

Enumeration and isolation of cellulolytic and hemicellulolytic bacteria from human feces.

The fibrolytic microbiota of the human large intestine was examined to determine the numbers and types of cellulolytic and hemicellulolytic bacteria present. Fecal samples from each of five individuals contained bacteria capable of degrading the hydrated cellulose in spinach and in wheat straw pretreated with alkaline hydrogen peroxide (AHP-WS), whereas degradation of the relatively crystalline...

Isolation and Identification of Tannin-degrading Bacteria from Native Sheep and Goat Feces in Kohgiloye and Boyer-Ahmad Province

Oak trees cover a wide range of forests in Iran and most of them are located in Kohgiloye and Boyer-Ahmad province (K.B). The high tannin is one of the anti-nutritional characteristics of acorn for domestic animal. Wide range of gut microorganisms could tolerate tannin and reduce it by producing tannase enzyme. This study was carried out to isolate and identify the tannin resistance bacteria (t...
