Brevibacterium frigoritolerans, a strain quite potential use in environmental pollution, is also able to degrade the pesticide phorate. Here, we report a strain isolated from radioactive soil in the Xinjiang Uygur Autonomous Region of China. The genome of strain GD44 encompasses 5,471,331 base pairs with a GC content of 40.42%. The sequence was assembled into 1985 open reading frames (ORFs) encoding 5053 proteins. Sequence analysis identified the genes encoding enzymes related to the degradation of organophosphorus compounds such as esterase, phosphotransferase, C-P lyase, and alkaline phosphatase. The nitrate reductase gene was also found in GD44, which was associated with biosynthesis of silver nanoparticles used for bacteriostat. In addition, Antibiotic Resistance Ontology (ARO) genes accounted for 10.6%, including the vancomycin resistance gene cluster. Therefore, the whole-genome sequence of B. frigoritolerans GD44 will be beneficial for identifying and analyzing genes utilized for soil remediation and antibacterial agent, which will provide genetic evaluation for potential application in the future.
耐冷短杆菌是一种很有应用潜力的环境污染治理菌,也能降解农药磷胺。本文报道了一株从中国新疆放射性土壤中分离得到的耐冷短杆菌。菌株 GD44 的基因组大小为 5471331bp,GC 含量为 40.42%。序列组装得到 1985 个开放阅读框(ORFs),编码 5053 个蛋白。序列分析鉴定了与有机磷化合物降解相关的酶基因,如酯酶、磷酸转移酶、C-P 裂合酶和碱性磷酸酶。GD44 中还发现了硝酸还原酶基因,该基因与用于抑菌的银纳米粒子的生物合成有关。此外,抗生素耐药性本体(ARO)基因占 10.6%,包括万古霉素耐药基因簇。因此,耐冷短杆菌 GD44 的全基因组序列有助于鉴定和分析用于土壤修复和抗菌剂的基因,为未来的潜在应用提供遗传评估。
