摘  要:
[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.
