摘  要：
[目的]探究制药废水中活的但非可培养(viable but non-culturable,VBNC)状态细菌的组成与系统关系。[方法]利用土质滤材构建生物反应器,基于复苏促进因子(resuscitation promoting factor,Rpf)对VBNC细菌的复苏刺激生长作用,采用MPN(most probable number)法,稀释平板法分离其中复苏可培养化的VBNC菌株并解析其16S rRNA基因系统关系。[结果]在MPN培养系中,Rpf对部分细菌有生长刺激作用。制药废水中存在对Rpf敏感、复苏可培养化的VBNC优势菌群;制药废水中对Rpf敏感的VBNC优势细菌主要有革兰氏阳性放线菌Microbacterium、Gordonia和Leucobacter属近缘菌,革兰氏阴性菌Candidimonas、Xanthobacter和Aminobacter属近缘菌,其中菌株ZYM1、ZYM3、ZYZR4和ZYXR1可能属于新种。[结论]研究结果揭示了制药废水中存在VBNC状态细菌,为研究其形成机理、复苏活性化机制以及制药废水的深度处理等提供重要的思路与方法。

摘  要：
[Objective] To investigate the composition and phylogenetic relationship of viable but non-culturable bacteria in pharmaceutical wastewater. [Method]Applied soil filter to build the bioreactor,then used resuscitation promoting factor( Rpf) which promoted the resuscitation and growth of VBNC bacteria,combined with most probable number( MPN) method and dilution plating to isolate the VBNC bacteria and analyzed 16S rRNA gene phylogenetic relationship. [Result]In MPN culture system,Rpf could promote the resuscitation and growth of some bacteria. There were VBNC advantage floras that sensitive to Rpf in pharmaceutical wastewater. The major culturable VBNC bacteria in pharmaceutical wastewater belonged to the high GC gram positive actinomycetes including genera Microbacterium,Gordonia and Leucobacter,and negative bacteria including genera Candidimonas,Xanthobacter,Aminobacter. There were 4 strains ZYM1,ZYM3,ZYZR4 and ZYXR1 could be potential novel species. [Conclusion]This research revealed there were VBNC bacteria in pharmaceutical wastewater. These results can provide important ideas and methods for further study on VBNC bacteria of the pharmaceutical wastewater,especially the formation mechanism and recovery mechanism of VBNC bacteria and the advanced degradation process improvement of pharmaceutical wastewater.
