Abstract

Pseudaminobacter manganicus JH-7^T (= KCTC 52258^T = CCTCC AB 2016107^T) is a Gram-staining-negative, aerobic and non-motile strain that was isolated from a manganese mine. The strain JH-7^T shows multiple heavy metal resistance and can effectively remove Mn²⁺ and Cd²⁺. In addition, it is able to produce exopolysaccharides (EPS), which may contribute to metal remove/adsorption. Thus, strain JH-7^T shows a great potential in bioremediation of heavy metal-contaminated environment. In this study, we report the draft genomic sequence of P. manganicus JH-7^T and compare it to related genomes. Strain JH-7^T has a 4,842,937 bp genome size with a G + C content of 61.2%, containing 4504 protein-coding genes and 71 RNA genes. A large number of putative genes associated with heavy metal resistance and EPS synthesis are found in the genome.

耐多种重金属细菌锰假单胞菌 JH-7T 的高质量草拟基因组序列。

锰假单胞菌 JH-7T（= KCTC 52258T = CCTCC AB 2016107T）是从锰矿中分离出来的革兰氏染色阴性、需氧、非运动菌株。菌株 JH-7T 对多种重金属具有抗性，能有效去除 Mn2+ 和 Cd2+。此外，它还能产生外多糖（EPS），这可能有助于去除/吸附金属。因此，菌株JH-7T在重金属污染环境的生物修复中显示出巨大的潜力。本研究报告了锰酸杆菌 JH-7T 的基因组序列草案，并将其与相关基因组进行了比较。菌株 JH-7T 的基因组大小为 4,842,937 bp，G + C 含量为 61.2%，包含 4504 个蛋白质编码基因和 71 个 RNA 基因。基因组中发现了大量与重金属抗性和 EPS 合成有关的假定基因。
