Özet

Plant biomass is the main diet of the herbivores and their biodegradation in the gastrointestinal tract of the animals is mainly depends on the fibrolytic activities of the gut microbes. Some plant sources, however, contain various anti-nutritional factors, such as tannins, which retards the digestion of the ingested plant particles by host animals. The current study explored the possible effects of the tannic acid on the growth rate and fibrolytic enzyme activities of five rumen originated anaerobic bacterial strains, Ruminococcus albus SY3, Fibrobacter succinogenes S85, Streptococcus bovis ES1, Prevotella bryantii B14, Butyrivibrio fibrisolvens JW11. Parallel with an increase in tannic acid concentration (0.1-0.6%) used in the culture medium, growth rates of all bacterial strains were notably reduced. Similar results were obtained for the CMCase and xylanase activities of those strains that various concentration levels (0.05-0.30%) of tannic acid hampered the activity of these fibrolytic enzymes significantly.
