摘要
为探讨乳酸菌添加剂对香蕉叶青贮发酵品质及单宁含量的影响,本试验以香蕉叶为原料,分别添加9株植物乳杆菌Lactobacillus plantarum (1×10~6cfu/g,LP)并以不使用添加剂为对照组(CK)进行青贮。结果表明:9株乳酸菌添加剂对香蕉叶单宁含量未产生显著影响,但显著增加了香蕉叶饲料中的乳酸含量,同时降低了pH值、NH_3-N和丁酸含量,在一定程度上改善了青贮发酵品质。
To investigate the effects of lactic acid bacteria strains on the fermentation quality and tannin content of banana leaves silage,the material was added 9 Lactobacillus plantarum( 1×106cfu/g,LP) strains. The results showed that: nine strains of lactic acid bacteria had no significant effect on tannin content of banana. However,Lactic acid content was significantly increased,while p H value,NH3-N and butyric acid content were decreased. Silage fermentation was improved by addition of LP.
