聚乙烯醇降解菌HK1菌株鉴定与降解特性
Identification and Degradation Character of a Polyvinyl Alcohol Degradable Bacteria HK1
摘要
Abstract
[Objective] The aim was to identify a polyvinyl alcohol degradable bacteria HK1 and study its degradation character.[Method] We took a strain HK1 which could grow with polyvinyl alcohol as the only carbon source,identified it through its morphology and physiochemical characteristics,studied the resistance to several kinds of antibiotics which were commonly used in the laboratory,and studied its degradation character through shake flask test.[Result] According to its morphology,physiochemical characteristics and 16S rDNA sequence analysis,HK1 was identified as Bacillus amyloliquefaciens.It could degrade 36.26% of PVA (1 g/L) after culturing at 30 ℃,180 r/min in shaking flasks.The optimal conditions for PVA biodegradation by the obtained strain were as followed:30 ℃,1 g/L PVA,pH 8.0,and 2 g/L yeast.[Conclusion] The results can provide reference for further research of the strain.关键词
