[Advances and Challenges in Biosafety Research for Urban Environments].

The global emergence of infectious diseases significantly threatens biosafety and human health. Anthropogenic activities, including rapid urbanization, agricultural intensification, global trade, and travel, are major drivers of zoonotic disease emergence. Emphasizing on the nexus of human, animal, and environmental health, the 'One Health' approach has been widely accepted for managing and preventing zoonoses.

[Reductive Dechlorination of Trichloroethylene by Benzoate-Enriched Anaerobic Cultures].

Gas chromatography was used to monitor the reductive dechlorination of trichloroethylene (TCE) by anaerobic enrichment cultures with benzoate as the sole carbon source. The 454 pyrosequencing technique was used to investigate the microbial community and the real-time quantitative PCR was used to quantify the gene copies of Dehalococcoides spp. (DHC).

[Analysis of Prokaryotic Community Structure in River Waters of the Ningbo Sanjiang Mouth].

The prokaryotic community structure in river waters of the Ningbo Sanjiang Mouth was analyzed for the first time using 16S rRNA gene based-Illumina Miseq high-throughput sequencing. A total of 215 504 high-quality sequences were obtained, and the results of alpha-diversity analysis revealed that Yongjiang River Watershed (YRW) harbored high diversity and richness of prokaryotic communities. Taxonomic assignment analysis indicated that β-Proteobacterium, Actinobacteria and Bacteroidetes dominated in the river water of YRW, and accounted for 78.

[Distribution of potential pathogenic bacteria in the Jiulong River Watershed].

Recently, the human activities including economic growth and urbanization posed serious environmental health risks to the Jiulong River Watershed (JRW). In order to gain a full understanding of the distribution of potential pathogenic bacteria (PPB) in this area, we used 16S rRNA amplicon pyrosequencing technology to investigate planktonic and benthic bacterial community in two main tributaries (North River, NR, and West River, WR) of the Jiulong River (JR). At the genus level, a total of 68 genera of PPB were identified in JR, which accounted for 6.
