Shotgun metagenomic sequencing of biofilm in an upflow fixed-film microaerophilic bioreactor system treating raw textile effluent

The biofilm metagenome from an upflow fixed-film microaerophilic-aerobic bioreactor system treating raw textile effluent was characterized for functional genes and biodegradation pathways. Novel bacterial oxido-reductases/azo reductases for biodegradation of textile dyes were identified in the bioreactor biofilm community. The taxonomic assignment of the biofilm metagenome revealed the presence of bacterial genera having ability for degradation of persistent organic pollutants and textile dyes.
