Alicycliphilus denitrificans strain BC and A. denitrificans strain K601(T) degrade cyclic hydrocarbons. These strains have been isolated from a mixture of wastewater treatment plant material and benzene-polluted soil and from a wastewater treatment plant, respectively, suggesting their role in bioremediation of soil and water. Although the strains are phylogenetically closely related, there are some clear physiological differences. The hydrocarbon cyclohexanol, for example, can be degraded by strain K601(T) but not by strain BC. Furthermore, both strains can use nitrate and oxygen as an electron acceptor, but only strain BC can use chlorate as electron acceptor. To better understand the nitrate and chlorate reduction mechanisms coupled to the oxidation of cyclic compounds, the genomes of A. denitrificans strains BC and K601(T) were sequenced. Here, we report the complete genome sequences of A. denitrificans strains BC and K601(T).
酸硫环菌 BC 株和酸硫环菌 K601(T) 株能够降解环状烃类物质。这两株菌均分离自污水处理厂材料和苯污染土壤的混合物以及一个污水处理厂，这表明它们在土壤和水的生物修复中具有作用。尽管这两株菌在系统发育上密切相关，但在生理特性上有明显差异。例如，菌株 K601(T) 可以降解环己醇，而 BC 株则不能。此外，这两株菌都可以利用硝酸盐和氧气作为电子受体，但只有 BC 株可以利用氯酸盐作为电子受体。为了更好地理解与环状化合物氧化相偶联的硝酸盐和氯酸盐还原机制，我们对酸硫环菌 BC 株和 K601(T)株的基因组进行了测序。在这里，我们报道了酸硫环菌 BC 株和 K601(T)株的全基因组序列。
