TCE reductive dechlorination  consortium
This study aimed to characterize the microbial community responsible for the complete reductive dechlorination of trichloroethene (TCE) to ethene. An anaerobic enrichment culture was established by dilution-to-extinction from chloroethene-contaminated soil collected in Zhangjiagang, Jiangsu Province, China. The culture was cultivated for over one year in DCB-1 mineral medium supplemented with acetate, hydrogen, and TCE. Metagenomic sequencing was performed on an Illumina NovaSeq platform, followed by assembly and genome binning. A high-quality metagenome-assembled genome (MAG) affiliated with Dehalogenimonas sp., named MAG_dhgm_Z1, was recovered and analyzed. The genome comprises 1.84 Mb across 61 contigs, with 97.18% completeness and 1.41% redundancy. Functional annotation revealed 33 putative reductive dehalogenase (RDase) genes, highlighting its potential role in organohalide respiration.
