Bacteria within the genus Alcaligenes, exhibit diverse properties but remain largely unexplored at genome scale. To shed light on the genome structure, heterogeneity and traits of Alcaligenes species, the genome of a tannery effluent isolated Alcaligenes faecalis subsp. phenolicus MB207 was sequenced and assembled. The genome was compared to the whole genome sequences of genus Alcaligenes present in the National Centre for Biotechnology Information database. Core, pan and species specific gene sequences i.e. singletons were identified. Members of this genus did not portray exceptional genetic heterogeneity or conservation and out of 5,166 protein coding genes from pooled genome dataset, 2429 (47.01%) contributed to the core, 1193 (23.09%) to singletons and 1544 (29.88%) to accessory genome. Secondary metabolite forming apparatus, antibiotic production and resistance was also profiled. Alcaligenes faecalis subsp. phenolicus MB207 genome consisted of a copious amount of bioremediation genes i.e. metal tolerance and xenobiotic degrading genes. This study marks this strain as a prospective eco-friendly bacterium with numerous benefits for the environment related research. Availability of the whole genome sequence heralds an opportunity for researchers to explore enzymes and apparatus for sustainable environmental clean-up as well as important compounds/substance production.
在产碱杆菌属内的细菌,表现出不同的特性,但在基因组规模上仍在很大程度上未被探索。为了阐明产碱杆菌属物种的基因组结构、异质性和特征,对从制革厂废水分离出的产碱杆菌亚种酚类 MB207 进行了测序和组装。将基因组与国家生物技术信息中心数据库中存在的产碱杆菌属的全基因组序列进行了比较。鉴定了核心、泛和种特异性基因序列,即单核苷酸多态性。该属的成员没有表现出特殊的遗传异质性或保守性,在汇总基因组数据集中的 5166 个蛋白质编码基因中,2429 个(47.01%)属于核心基因,1193 个(23.09%)属于单核苷酸多态性基因,1544 个(29.88%)属于附加基因组。还对次生代谢产物形成装置、抗生素产生和抗性进行了分析。产碱杆菌亚种酚类 MB207 基因组包含大量生物修复基因,如金属耐受性和异生物质降解基因。这项研究将该菌株标记为一种具有众多环境相关研究益处的有前途的环保细菌。全基因组序列的可用性为研究人员提供了探索可持续环境清洁用酶和装置以及重要化合物/物质生产的机会。
