Determination of Hydrogen Peroxide Photoproduction by a Marine Cyanobacterium Oscillatoria boryana BDU 92181 with Potential Use in Bioremediation
The present study was aimed to find out the ability of the marine cyanobacterium Oscillatoria boryana BDU 92181 to produce H2O2 and to optimize its photoproduction with a view to harness its potential for decolorization of distillery effluent. The organism decolorized distillery effluent (5% V/V) by about 60% in 30 days. The mechanism of decolorization is postulated to be due to the production of hydrogen peroxide and molecular oxygen released by the cyanobacterium during photosynthesis. The effects of light intensity as well as different enhancers and inhibitors on the production of H2O2 in this organism were studied. Our results showed that, riboflavin and MnSO4 positively influenced H2O2 production. Sodium metabisulphite and potassium cyanide inhibited H2O2 production.
