Role of biofilms and arsenite in the adaptation and genomic variability of the Thiomonas bacteria involved in natural mine drainage remediation

After exposure to arsenic, when grown in a biofilm, Thiomonas sp. CB2 develop variants that are more resistant to arsenic. 3 variants were selected for genome sequencing and comparison with the original CB2 strain.

当暴露于砷（arsenic）环境并以生物被膜（biofilm）形式生长时，单胞菌属（Thiomonas）菌株CB2可产生对砷具有更高抗性的变异株。本研究选取3株该变异株进行基因组测序（genome sequencing），并与原始CB2菌株开展对比分析。
