摘要
苯胺黑药高效降解菌(Bacillus vallismortis sp.)与重金属之间存在相互作用.本文通过改变Zn2+、Cu2+对菌株的胁迫时间和胁迫强度,考察菌株胞外聚合物(EPS)在两种金属胁迫下的产量和组分变化,并进一步研究获得的特异性EPS的吸附性能.结果表明:Zn2+和Cu2+的胁迫强度分别为12mg/L和6mg/L时,EPS产量分别增加至100.835mg/g VSS和60.65mg/g VSS;在一定胁迫范围内,两种金属均能刺激菌株产生更多特异性EPS,为金属离子提供大量结合点位,显著提高了重金属去除能力,对应用生物法处理同时含有有机物和重金属的复合型废水具有一定的指导意义。
Several interactions exists between Bacillus vallismortis sp. and heavy metals. In this paper, Bacillus vallismortis sp. was used as the test strain to explore the effect of heavy metals on the components and adsorption ability of EPS. The results showed that the production of EPS increased to 100.835mg/g VSS and 60.65mg/g VSS under 12mg/L Zn~(2+) and 6mg/L Cu~(2+) exposures, respectively. Both of two metals can prompt the production of EPS and as a result it could improve ability of EPS to bind heavy metals. These results might provide a theoretical guidance for the application of biological technique of dealing with compound wastewater which containning organics and heavy metals.
