Tannin-tolerant ruminal bacteria from East African ruminants

Three strains of tannin-tolerant rumen bacteria were isolated from enrichment cultures of rumen microflora of sheep, goat, and antelope and established in medium containing high concentrations of crude tannin extract or tannic acid. These three strains (EAT2, ES3, and EG19), characterized as Selenom...

description Three strains of tannin-tolerant rumen bacteria were isolated from enrichment cultures of rumen microflora of sheep, goat, and antelope and established in medium containing high concentrations of crude tannin extract or tannic acid. These three strains (EAT2, ES3, and EG19), characterized as Selenomonas species, were curved rods, obligately anaerobic, Gram negative, highly motile, and grew in media containing 50 g of tannin extract/L and 50-70 g of tannic acid/L. Strain EAT2 was able to hydrolyze garlic acid, while strains ES3 and EG19 hydrolyzed tannic acid but not gallic acid. All isolates were able to grow in media containing up to 8 g of condensed tannins/L. Growth was very slow when soluble carbohydrate was not added to the medium.
