西藏青贮用乳酸菌筛选分离及应用研究进展

西藏自治区地处青藏高原,虽然饲料原料资源丰富,但整体利用率不高。青贮处理可以有效贮存饲料,既可以节约饲料资源,也可以保存饲料中的营养成分。目前,西藏地区关于青贮用乳酸菌的研究已经由从传统乳制品中分离乳酸菌过渡到从多种天然青贮饲料中分离乳酸菌。对西藏地区青贮用乳酸菌的筛选分离及应用研究进展进行了综述,以期为加快以青贮分离乳酸菌菌株为来源的高原青贮用乳酸菌制剂的研发提供参考。

Research Advances on the Screening,Isolation and Application of Lactic Acid Bacteria for Silage in Tibet

Tibet Autonomous Region is located on the Qinghai-Tibet Plateau. Although the feed resources are abundant, the overall utilization is limited. Silage treatment can effectively store feed, save feed resources and preserve the nutrients in feed. At present, the researches on lactic acid bacteria for silage in Tibet have transitioned from separating lactic acid bacteria from traditional dairy products to separating lactic acid bacteria from a variety of natural silage. The research advances on the screening, isolation and application of lactic acid bacteria for silage in Tibet are reviewed, in hoping to provide references for accelerating the research and development of lactic acid bacteria preparations for silage production in plateau using lactic acid bacteria strains isolated from natural silage.
