Methylomicrobium strains are widespread in saline environments. Here, we report the complete genome sequence of Methylomicrobium alcaliphilum 20Z, a haloalkaliphilic methanotrophic bacterium, which will provide the basis for detailed characterization of the core pathways of both single-carbon metabolism and responses to osmotic and high-pH stresses. Final assembly of the genome sequence revealed that this bacterium contains a 128-kb plasmid, making M. alcaliphilum 20Z the first methanotrophic bacterium of known genome sequence for which a plasmid has been reported.
产甲烷菌广泛存在于盐环境中。在这里,我们报告了一株嗜碱产甲烷菌甲基微菌 20Z 的全基因组序列,该菌是一种 haloalkaliphilic methanotrophic bacterium,它将为阐明其碳代谢和应对渗透压及高 pH 值胁迫的核心途径提供基础。基因组序列的最终组装表明,该菌含有一个 128kb 的质粒,这使得甲基微菌 20Z 成为首个已知基因组序列的产甲烷菌,其质粒已被报道。
