Abstract
Tannin–protein complex degrading bacteria after enrichment were isolated from unadapted goat faecal samples. Based on the morphological, hemolytic and biochemical characters, the isolates were categorized in two groups comprising GF1–GF4 and GF5–GF6. All the isolates were gram-positive cocci, catalase negative belonging to different strains of Group D streptococci, Enterococcus faecalis. Among six isolates, GF1 was the most resistant that could tolerate up to 4% of tannic acid in the medium with no significant change in the morphology. Tannase activity was detected in all the isolates, indicating their tannin degrading potential while gallate decarboxylase activity was detected only in three isolates GF1, GF2 and GF6.
