| 摘 要： | 根据聚乙烯醇与碘的作用机理确定了聚乙烯醇降解酶产生菌的筛选原理，并在此基础上对从无锡、上海和贵阳等地采集的样品进行分离，得到53株能够产生PVA降解酶的菌株，通过菌落形态及一系列生理生化实验对这些菌株进行了初步鉴定，同时利用生物多样性指数法对PVA降解酶产生菌的物种丰富度进行了分析。结果初步说明了PVA降解酶产生菌在自然界的分布具有普遍性。

| Abstract: | Based on the mechanism of PVA reacted with I_(2), the screening principles of PVA-degrading enzyme producing microorganisms were determined. Based on these principles, 53 microbes were screened from samples collected at Wuxi, Shanghai and Guiyang. The cellular morphology, physiological and biochemical characteristics of these microbes were identified, respectively. In addition, the biologica1 diversity index was used to analyze the species richness. The results indicated that, the PVA-degrading enzyme producing organisms are extensively and universally distributed in nature. |
