The invention provides the isolated microorganism Lactobacillus plantarum TAK 59 NCIMB42150, which is used for accelerating the fermentation of feed, for increasing the concentration of lactic acid and for reducing pH, hence decreasing the loss of nutrients in feed. L. plantarum TAK 59 decreasess the concentration of ammonia nitrogen and butyric acid in feed. Usage of the microorganism in ensiling suppresses the function of proteolytic and pathogenic microorganisms (enteropathogens and Clostridium) in feed. Lactobacillus plantarum TAK 59 can be used as silage additive in easy and moderately difficult to ensile forage and for prolonging the storage life of feed.
