Mycoremediation and toxicity assessment of textile effluent pertaining to its possible correlation with COD

Abstract Globally, textile industries are one of the major sectors releasing dye pollutants. This is first report on positive correlation between toxicity and chemical oxygen demand (COD) effluent along with proposed pathway for enzymatic degradation acid orange 10 using Geotrichum candidum within a very short stretch time (18 h). Removal efficiency this mycoremedial approach after 18 h in terms demand, biological total suspended solids, salinity, color concentration treated reached to 98.5%, 56.3%,73.2%, 64%, 89% 87% respectively. Also there was decrease pH effluent. FTIR analysis confirmed biodegradation. The LCMS showed 10, which by formation two biodegradation products, 7-oxo-8-iminonapthalene-1,3-disulfonate nitrosobenzene, subsequently undergoes stepwise hydrogenation dehydration form aniline via phenyl hydroxyl amine as intermediate. X-ray diffraction studies that heavy metal content has reduced % crystallinity, indicating connection COD also inveterated Pearson’s coefficient. Further toxicological indicated raw relatively lower toxic nature metabolites generated G. .
