Genomic analysis of carbon dioxide sequestering bacterium for exopolysaccharides production.

ABSTRACT: In the present study, genomic analysis of a previously reported carbon dioxide (CO₂) sequestering bacterium Serratia sp. ISTD04 was performed along with exopolysaccharide (EPS) production. Genomic analysis identified key and accessory enzymes responsible for CO₂ sequestration. EPS synthesis genes were discovered in the genome and identified 8 putative clusters responsible for lipopolysaccharide, stewartan, emulsan, polysaccharide B, capsular polysaccharide and fatty acid-saccharide production. The production of EPS was found to be 0.88 ± 0.08, 1.25 ± 0.13 and 1.44 ± 0.10 g L^-1 on glucose, bicarbonate (NaHCO₃) and NaHCO₃ plus glucose respectively at pH 7.8. After optimizing process parameters, the EPS production increased more than 3 fo
