Bacillus subtilis SR1 is a metal resistant, polyaromatic hydrocarbon-degrading bacterium isolated from petroleum contaminated sites. This study reports the characteristics of the genome of the isolate containing one circular chromosome (4,093,698 bp) annotated into 4155 genes and 4095 proteins. The genome analysis confirmed the presence of multiple catabolic genes: aromatic ring-hydroxylating dioxygenase (COG2146), aromatic ring hydroxylase (COG2368), catechol 2, 3 dioxygenase (COG2514), 4-hydroxybenzoate decarboxylase (COG0043), carboxymuconolactone decarboxylase (COG0599) responsible for the catabolism of aromatic hydrocarbons along with the genes for biosurfactant production and functional genes (czcD and cadA) for resistance to cadmium, zinc, and cobalt. Gas Chromatography-Mass spectroscopy analysis revealed up to 35% in-vitro degradation of benzo(a)pyrene after 21 days of growth along with the production of different intermediate metabolites. The pot trial analysis in the greenhouse condition validated the rhizodegradation of BaP, which was significantly higher in the presence of plant-microbe association (85%) than degradation in bulk soil (68%).

枯草芽孢杆菌SR1 是一种从石油污染场地分离出来的耐金属、多环芳烃降解细菌。该研究报告了分离株的基因组特征，该分离株含有一条环状染色体（4,093,698 bp），注释为 4155 个基因和 4095 个蛋白质。基因组分析证实存在多个分解代谢基因：芳环羟基化双加氧酶(COG2146)、芳环羟化酶(COG2368)、儿茶酚 2、3 双加氧酶(COG2514)、4-羟基苯甲酸脱羧酶(COG0043)、羧基粘酸内酯脱羧酶(COG0599) 负责芳香烃的分解代谢，以及产生生物表面活性剂的基因和抗镉、锌和钴的功能基因（czcD和cadA）。气相色谱-质谱分析显示，在生长 21 天后，苯并 ( a ) 芘的体外降解率高达 35%，同时产生了不同的中间代谢物。温室条件下的盆栽试验分析验证了 BaP 的根际降解，在存在植物-微生物关联的情况下 (85%) 明显高于在大块土壤中的降解 (68%)。
