摘要
采用常规稀释法和划线纯培养法 ,从三个污泥样中分离出 1 94株细菌 ,经过初筛和复筛获得 1 4株产高效 MBF的菌种。它们所产 MBF对所选四种废水均有一定的处理效果。在对各菌株进行絮凝活性的遗传稳定性检验后 ,得到 -4 1菌株 ,其为小细杆状 ,革兰氏染色阳性的兼性厌氧菌。伴随试验过程获得了产
Among 194 bacterial strains isolated from three representative sludge samples, 14 strains, which could produce efficient MBF, were obtained after screening and re-screening. These MBF had shown positive effects on treatment of four kinds of selected wastewater. However, after examining the hereditary stability of flocculation activity for bacteria, most of the strains lost their ability in producing effective MBF except for the I-41 strain. The I-41 is a bacillus G + amphibacterium. Meanwhile, the model of MBF-producing bacteria is found in this trail program.
