摘要
从绍兴水处理发展有限公司的曝气池污泥中筛选到6株聚乙烯醇(PVA)降解功能菌株,编号为rF1、rF2、rF3、rF4、rF5和rF6。通过16S rDNA测序比对表明其分别为Pseudochrobactrum sp、解淀粉芽孢杆菌(Bacillus amyloliquefaciens)、芽孢杆菌(Bacillus sp)、门多萨假单胞菌(Pseudomonas mendocina)、杆菌属(Lysinibacillus sp)、不动杆菌(Acinetobacter sp)。在自配培养基中,有3株菌PVA降解率可达70%~80%,在印染废水中,有5株菌PVA降解率可达到90%以上。其中r F1、r F2和r F5无论是在自配培养基还是印染废水中都具有较好效果,表明具有一定的实际应用价值。
Six polyving akohol( PVA) degrading strains were isolated from the biological aeration tank sludge of Shaoxing Water Treatment Development Co.,Ltd. and numbered for rF1,rF2,rF3,rF4,rF5 and rF6 respectively. The 16 S rDNA identification indicated that they were Pseudochrobactrum sp,Bacillus amyloliquefaciens,Bacillus sp,Pseudomonas mendocina,Lysinibacillus sp,and Acinetobacter sp. The PVA degradation rate of three strains could reach 70% ~ 80% in the mixed medium while five of them were more than 90% in the printing and dyeing wastewater. In matter in the mixed medium or the printing and dyeing wastewater,rF1,rF2 and rF5 both had good PVA degradation effect,showing they had a certain practical application value.
