[Objective] To provide a reference for scientific and rational utilization of forage silage.[Method] The number and species of microorganisms in forage were analyzed,and the characteristics of 11 strains of lactic acid bacteria(LAB) were studied.[Result] All the isolates were Gram-positive,catalase negative and aeroanaerobic.The isolated strains of homofermentation accounted for 78%.The isolates were divided into three groups,Lactobacillus,Leuconostocaceae and Lactococcus,according to their morphological and biochemical characters.[Conclusion] The microorganisms in forage in northwest China were isolated and identified,which provides a scientific basis for utilization of forage silage.
[Objective] To provide a reference for scientific and rational utilization of forage silage. [Method] The number and species of microorganisms in forage were analyzed, and the characteristics of 11 strains of lactic acid bacteria (LAB) were studied. the isolates were Gram-positive, catalase negative and aeroanaerobic. Isolated from homofermentation accounted for 78%. The isolates were divided into three groups, Lactobacillus, Leuconostocaceae and Lactococcus, according to their morphological and biochemical characters. [Conclusion] The microorganisms in forage in northwest China were isolated and identified, which provides a scientific basis for utilization of forage silage.
