A The fungal strains displaying the ability to hydrolyze cellulose, gelatin, casein, and dissolve CaCO3. The clear zones observed on the agar plates indicate the degradation ability, which decreases progressively from left to right in the figure. B The turbidity in tubes reflected the degradation of keratin.
