| 摘 要： | 研究了不同金属离子及其添加形式对肺炎克雷伯氏菌胞内酶和胞外酶降解三苯基锡的影响,以期为阐明有机锡的酶促降解机制提供实验依据.结果表明,菌体对K+、Mg2+、Cu2+、Ca2+、Fe3+具有良好的耐受能力,高浓度的Zn2+、Fe2+可能对菌体产生一定的毒害作用,从而影响其生长.适当浓度范围的K+、Mg2+、Zn2+、Cu...

| Abstract: | The influence of different metal ions and different forms of addition on triphenyltin enzymatic degradation was investigated under conditions using enzyme obtained from Klebsiella pneumoniae.The objective of this study is to illuminate the mechanism of enzymatic degradation of triphenyltin(TPhT).The results demonstrated that the strain was able to tolerate K +,Mg2 +,Cu2 +,Ca2 + and Fe3 + at high concentrations.High concentrations of Zn2 + and Fe2 + had some toxic effects on the strain,thus affecting its gro... |
