Biodegradation of naphthalenesulfonic acid by means of selected mixed bacterial culture

In this work was investigated activity of selected mixed bacterial culture for 6-aminonaphthalene-2-sulfonic acid (6AN2SA) biodegradation, at microaerophilic conditions. Experiments were carried out at defined parameters: concentration of 6AN2SA 500-700 mg/L, dissolved oxygen 0.2-0.4 mg/L and microbial biomass concentration 0.5-1 g/L. Complete 6AN2SA degradation was determined by measuring of 6AAN2SA concentration, TOC-value, COD-value, total nitrogen and sulphate. In selected mixed bacterial culture dominated Pseudomonas strains. Degradation of 500 mg/L 6AN2SA by selected mixed bacterial cultures at microaerophilic conditions was achieved after 7 days.
