摘要
[目的]为动物角蛋白的高效、经济降解和利用提供新种质资源。[方法]采用传统分离筛选、固体基质降解和动物试验相结合的方法,对角蛋白降解菌进行了分离筛选及初步鉴定。[结果]得到1株非致病、降解效率较高的丝状真菌,并初步鉴定为毛霉科(Mucoraceae)的一个种。[结论]该菌株的发现丰富了角蛋白降解菌的家族成员,为动物角蛋白的降解利用提供了新种质资源。
[Objective] The paper was to provide new germplasm sources for efficient and economical degradation and utilization of animal keratin.[Method] The keratin-degrading fungus was isolated,screened and primarily identified by using the combination method of traditional isolation and screening,solid culture-medium degradation and animal test.[Result] A strain of non-pathogenic filamentous fungi with high degradation efficiency was obtained,which was preliminarily identified to be a species in Mucoraceae.[Conclusion] The discovery of the strain enriched the family members of keratin-degrading fungus,and provided new germplasm resources for degradation and utilization of animal keratin.
