Abstract:

从新疆荒漠土壤中分离筛选絮凝剂产生菌,得到一株对高岭土悬浊液具有较高絮凝活性的微生物絮凝剂产生菌W36-1,根据菌株的Biolog鉴定以及16SrRNA基因序列分析,确定为一株欧文氏菌属(Erwinia)新种。该菌絮凝产物的发酵动力学研究表明,其属于Ⅱ型发酵,即菌体生长和产物合成部分偶联;在发酵48h后絮凝活性最高,产量可达到6g/L;絮凝特性研究表明,在20~100℃范围内有较高的温度稳定性;在酸性环境条件下有较高的絮凝活性,pH值大于7,絮凝活性迅速下降;一些金属阳离子对絮凝有促进作用,其中,Ca2+的助凝效果最好,Mg2+次之,Al3+和Fe3+的助凝效果最差。该絮凝剂对水中各种重金属离子和色素具有较好的吸附去除作用,显示出其在环境工程中良好的应用前景。
