Congo red as an indicator and streptomycin (50 mg/L) (Miklaszewska et al., 2016).. Hypercellulolytic mutants were selected on the basis of the hydrolysis capacity (HC). The HC was calculated as the ratio of the diameter of cellulose hydrolysis zone marked by Congo red to the diameter of colony growing on a given cellulose medium.. Colonies with a HC value greater than 10%. compared to HC value of wild strain were considered as the potential mutants producing high cellulase..
