| 摘 要： | 采用透析的方法,研究了硫酸盐还原菌(SRB)及不同分子量(0~200、200~2 000、2 000~10 000)代谢产物与石膏接触时对其还原分解的影响。实验结果表明,SRB代谢产生了更多的碱性物质,导致体系pH值明显上升;随着SRB及其代谢产物与石膏的接触作用逐渐增强,石膏的还原分解能力逐渐提高;SRB及其代谢产物可以诱导形成具有良好结晶形态的方解石和无定形态碳酸盐沉淀;代谢产物除可促进石膏还原分解外,一定条件下也可抑制石膏溶解。研究结果表明,SRB及其代谢物与石膏的接触作用对其还原分解有一定的影响,影响机制主要为络合作用和营造pH值、HCO-3浓度不同于溶液的SRB-石膏界面微环境。
