In this study, 23 strains of <i>Aspergillus niger</i> were systematically investigated for their capability on production of carbohydrate-processing enzymes used in industries. The strains were grown on glucose or selected agricultural wastes comprising varied chemical compositions as the sole carbon source. As a control, glucose induced basal activities of amylase, pectinase, and xylanase in only a few strains, while the CMCase, β-glucanase, and invertase activities were detected only when the carbon source was switched to the agro-industrial biomass. According to one-way ANOVA analysis, banana peels containing lignocellulosic components with high 3 BiotechProfiling multi-enzyme activities of <i>Aspergillus niger</i> strains growing on various agro-industrial residues.PMC8671598P-18-52705Bunterngsook BChampreda VLaothanachareon TfalseProfiling multi-enzyme activities of <i>Aspergillus niger</i> strains growing on various agro-industrial residues.Agro-industrial wastes provide potential sources of carbon for production of fungal enzymes applied for various biotechnological applications.
