Abstract
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.
