Figure 10. Qualitative assessment of amylase activity of Pseudothielavia terricola on starch agar. Uninoculated control plate after iodine application showing blue–black staining (A). Representative plates from three independent replicates of P. terricola after five days of incubation and iodine application, showing clear hydrolysis halos surrounding the colonies, indicating starch degradation and amylase production (B–D). Scale bar = 5 cm.
