Little mycelia were picked out from the purified plates and inoculated to cellulose congo-red agar plates. After 5 days of incubition at 30°C, hydrolysis zones of different sizes were observed clearly on plates (Hendricks et al., 1995). Carboxymethyl cellulase activities were estimated roughly by their ratios of diameter of hydrolysis zones and colonies (Xu and Yang, 2010), and those with high ratio values were selected and stored on slants at 4°C for the further detection of activities of other enzymes.
