Abstract:

研究了克雷伯氏菌在无机盐培养基和去离子水中对三苯基锡(TPhT)的降解性能,考察了不同时间TPhT降解率与各离子释放量的变化关系,为论证有机锡的微生物降解机理提供实验依据.5.0g·L-1菌体处理120h后,3.0mg·L-1TPhT在无机盐培养基和去离子水体系中的降解率分别高达77.3%和60.9%.在TPhT降解过程中,TPhT会促进菌体离子的释放,加剧菌体的内陷并增加凋亡细胞的数量.TPhT的降解率与NH4+、Na+、PO43-、SO42-、NO2-的释放在0.01水平下显著正相关,Na+、NH4+、Ca2+的释放规律符合准二级动力学模式.XPS分析证明菌体降解TPhT120h前后细胞表面元素和基团没有发生改变,但TPhT则发生了转化.
