摘　　要：本文从活性污泥中筛选到一株可以降解PLA的细菌DS04—W,通过形态学、生理生化性质以及16Sr DNA序列分析进行菌种鉴定,初步鉴定该菌为Bacillus megaterium(巨大芽孢杆菌),并且具有降解PLA的能力,这为进一步研究酶解PLA的机理奠定了基础。A strain possessing activity to degrade poly- L- lactic acid（ PLA） DS04- W was screened from sludge. It was identified by the analyses of morphological,physiological and biochemical properties,16 Sr DNA comparison. It was identified as Bacillus megaterium.Strains DS04＇- W has the ability of degradation PLA. It established the foundation for the further research on enzymic hydrolysis PLA.
