Pseudonocardia dioxanivorans CB1190 is the first bacterium reported to be capable of growth on the environmental contaminant 1,4-dioxane and the first member of the genus Pseudonocardia for which there is an annotated genome sequence. Preliminary analysis of the genome (chromosome and three plasmids) indicates that strain CB1190 possesses several multicomponent monooxygenases that could be involved in the aerobic degradation of 1,4-dioxane and other environmental contaminants.
假诺卡氏菌(Pseudonocardia)dioxanivorans CB1190 是第一株能够以环境污染物 1,4-二恶烷为唯一碳源生长的细菌,也是第一个具有注释基因组序列的假诺卡氏菌属成员。对基因组(染色体和三个质粒)的初步分析表明,CB1190 菌株拥有几种多组分单加氧酶,这些酶可能参与 1,4-二恶烷和其他环境污染物的有氧降解。
