Determination of Hydrogen Peroxide Photoproduction by a Marine Cyanobacterium Oscillatoria boryana BDU 92181 with Potential Use in Bioremediation

The goal of this study was to determine the ability of the marine cyanobacterium Oscillatoria boryana BDU 92181 to create H2O2 and to optimise its photoproduction in order to harness its potential for distillery effluent decolorization. In 30 days, the organism reduced the colour of distillery effluent (5 percent V/V) by around 60%. The formation of hydrogen peroxide and molecular oxygen by the cyanobacterium during photosynthesis is thought to be the cause of decolorization. On the generation of H2O2 in this organism, the effects of light intensity, as well as several enhancers and inhibitors, were investigated. Riboflavin and MnSO4 both had a favourable effect on H2O2 generation, according to our findings. H2O2 generation was suppressed by sodium metabisulphite and potassium cyanide.
