Abstract
针对高盐硫酸根废水的特性,从海底沉积物中富集得到1个硫酸盐还原菌菌群SRB.2,并研究了盐度、温度、pH值、碳源、硫酸根浓度和铁形态对其活性的影响.结果表明,SRB-2为嗜盐中温硫酸盐还原菌群,可以利用乙醇及乳酸为单一碳源,最佳生长温度为30~40℃,最佳生长pH值为7.4~8.3,SRB.2菌群能够在硫酸根浓度为5200mg/L或盐度为60g/L的条件下正常生长,还原铁粉对该菌群还原硫酸根的能力具有加强作用,而二价铁离子则抑制细菌活性.扫描电子显微镜及光学显微镜对菌体形态研究发现,在反应器填料表面,该菌群中有大量短竿状及螺旋状细菌黏附,而在底部,主要为表面覆盖大量黑色粘稠物质,由短竿状细菌组成,推测其可能是菌种SRB-2—64(GenBank序列号:EU167911)的堆积
