牛链球菌在瘤胃中产酸的代谢机制及调控
Metabolic Mechanism of Acid Production by Streptococcus bovis in Rumen and Its Regulation
摘要
Abstract
Streptococcus bovis ( S.bovis) is usually a major lactate producing bacterium in the rumen, and is recognized its’ contribution to development of rumen acidosis when ruminants are fed high concentrate diets. Previous work indicates that carbohydrate metabolism in S.bovis is mainly affected by the way of glucose trans membrane transport, and enzymes and intermediate metabolites in glycolytic pathway.In addition, the factors, environmental pH, growth stage, and control protein catabolism ( CcpA) , etc., also have significant impacts. In this paper, metabolic mechanism and influence factors of carbohydrate fermentation and acid production by S.bovis were reviewed in purpose to provide references for further insight into the mechanism of rumen acido-sis caused by lactic acids.关键词
