Small RNAs(sRNAs)are key players in the regulation of bacterial gene ***,the distribution and regulatory functions of sRNA in pig farm wastewater treatment plants(WWTPs)remains *** this study,the wastewaters in anoxic and oxic tanks of the WWTPs were *** profiles of the community structure,mRNA expression,and sRNA expression of bacteria in pig farm wastewater were investigated using transcriptome sequencing and *** study demonstrated that there was a higher abundance of sRNA in the pig farm WWTPs and 52 sRNAs were *** sRNAs were mainly present in Proteobacteria and Firmicutes,including the potential human pathogenic bacteria(HPB)(Escherichia,Shigella,Bordetella and Morganella),crop pathogen(Pectobacterium)and denitrifying bacteria(Zobellella).And the sRNAs were involved in the bacterial functional activities such as translation,transcription,drug resistance,membrane transport and amino acid *** addition,most sRNAs had a higher abundance in anoxic tanks which contained a higher abundance of the genes associated with infectious diseases and drug resistance than that in oxic *** results presented here show that in pig farm WWTPs,sRNA played an important role in bacterial function activities,especially the infectious diseases,drug resistance and denitrification,which can provide a new point of penetration for improving the pig farm WWTPs.

The microbial communities colonized on microplastics(MPs)have attracted widespread ***,few studies focused on the MPs impacts on mangrove ecosystems,particularly on bacterial *** investigated the MPs pollution in mangrove of Zhujiang(Pearl)River estuary(ZRE).To study the potential risk posed by MPs to the mangrove ecosystems,the differences in bacterial communities,functions,and complexity between MPs and sediment samples were reported for the first ***(2991±1586 items/kg dry weight(dw))in sediment were mainly fibers and polyethylene,mostly transparent,and in size less than 0.5 *** communities and functions significantly differed from MPs in mangrove *** with sediment,MPs significantly enriched members of Proteobacteria,Bacteroidetes,and Actinobacteria,as well as the bacteria associated with plastic-degrading and human diseases on their surface,suggesting that microbial communities on MPs may promote MPs degradation and the spread of diseases,posing potential risk to mangrove ecosystems and human *** bacteria on MPs exhibited a lower diversity,the co-occurrence network analysis indicated that network of bacteria colonized on MPs was bigger and more complex than those of mangrove sediment,illustrating that MPs can act as a distinct habitat in this special *** study provides a new perspective for increasing our understanding of microplastic pollution in mangrove ecosystems.
