| 摘 要： | 为研究好氧颗粒污泥中大量存在的芽孢对其环境耐受力的作用,将好氧颗粒污泥经过低温无营养、高温高压、冷冻和紫外线处理后,监测其活性恢复过程中2,6-吡啶二羧酸根(dpa)的释放、比耗氧速率(SOUR)和以还原2,3,5-氯化三苯基四氮唑(TTC)为标志的脱氢酶的活性变化.实验结果显示,好氧颗粒污泥中大量存在的芽孢在不良环境条件下处于休眠状态,环境条件改善后能迅速转化为繁殖体细胞,进行正常的代谢活动.作为潜在的生命力,好氧颗粒污泥对不良环境的耐受力增强.芽孢是好氧颗粒污泥不容忽视的重要组分.

| Abstract: | With the purpose of investigating the effects of bacteria spores on aerobic granules' tolerance to adverse conditions,granules which had been stored without nutrient supply,frozen,sterilized and radiated under UV light respectively,were studied by batch experiments.The dipicolinic acid (dpa) released from the granules,specific oxygen utilization rate(SOUR) and 2,3,5-Triphenyltetrazolium chloride(TTC) reducing ability were monitored.The results showed that spores inside aerobic granules contributed significa... |
