摘　　要：从相关环境中分离出霉菌10株，编号为M1～M10。采用固体琼脂平板培养法，液体摇瓶培养法，通过观察微生物在膜上的生长状况，测试膜失重以及FTIR检测羰基峰等方式对改性PE膜的生物降解性进行了研究。结果表明，M6菌可以附着于改性PE膜上，以改性PE膜为单一碳源在固体琼脂平板培养、液体摇瓶培养可见其生长繁殖，通过红外光谱检测，其羰基峰明显，证明了改性PE膜的生物可降解性。根据该菌的形态特征、培养特征等，初步鉴定其为黑曲霉属。Ten mould was isolated from relevant environments, numbered M1 -M10. The biodegradability of modified polyethylene （PE） fihn were studied by agar plate culture and shaking flask culture. The evaluation on biodegradability of film was measured by microbe growth state at film, the weightless of the film, and the carbonyl peak by Fourier transform infrared spectrometer （FHR）. The results showed that M6 mould could adhere onto modified PE film, and it could be seen growing with modified PE film as single carbon source by agar plate culture and shaking flask culture. The carbonyl peak measured by FTIR significantly higher indicated the biodegradability of modified PE. According to its morphology, cultural characteristics, M6 was identified as Aspergillus Niger.
