Calcium-mediated modulation of Pseudomonas mendocina NR802 biofilm influences the phenanthrene degradation

- The present study illustrates the involvement of divalent ions (Ca2+ and Mg2+) in biofilm mediated phenanthrene degradation.
- Biofilm forming potential of marine bacterium Pseudomonas mendocina NR802 was evaluated at various concentrations of Ca2+ and Mg2+.
- Increased exopolysaccharide production was observed when biofilm was grown in presence of 20 mM Ca2+.
- There was 15% increase in degradation of phenanthrene by biofilm grown in the presence of Ca2+.
- The finding propose essential role of Ca2+, biofilm and associated extracellular polymeric substances in biodegradation of organic pollutants in marine environment.
