为提高中草药饲料添加剂的抑菌效果和应用效果,从中草药青蒿、鱼腥草、地骨皮、黄岑、胆草、夏枯草等中草药中筛选到1株能发酵中草药饲料添加剂的菌株,鉴定为米曲霉Y-1.以抗菌活性和CMCase酶、FPA酶及蛋白酶酶活为评价指标,研究了以青蒿、鱼腥草、地骨皮、胆草等为主组成的中草药饲料添加剂的发酵条件.结果表明,合适的发酵条件为:中草药饲料添加剂与麦麸的比例为7∶3、葡萄糖1 %、发酵温度32 ℃、初始pH自然、物料含水量50 % ～ 60 %、发酵周期为72 h.在此条件下,发酵料蒸煮液对大肠杆菌、金黄色葡萄球菌、普通变形杆菌和鼠伤寒沙门氏菌的抑菌活性分别较对照提高36.03 %、60.83 %、27.64 %、41....

To improve the effects of antibacterial and application of Chinese herbal feed additive.A Chinese herbal feed additive fermenting strain was isolated from Chinese herbal such as Herba artemisiae annuae ,Herba houttuyniae, Cortex Lycii,Scutellaria baicalensis Georgi, Corallodiscus flabellate and Spica prunellae etc.It was preliminarily identified as Aspergillus orzyme Y-1.The fermentation conditions for Chinese herbal feed additive containing Herba artemisiae an- nuae ,Herba houttuyniae ,Cortex Lycii,Corallodiscus flabellate were studied with th...
