A High Diversity in Chitinolytic and Chitosanolytic Species and Enzymes and Their Oligomeric Products Exist in Soil with a History of Chitin and Chitosan Exposure

Figure 1

Chitinolytic and chitosanolytic activities in bacterial and fungal isolates from soil samples. (a) Bacterial strains showing clearing zones on minimal medium agar plates containing colloidal chitin; one strain showing weak chitinolytic activity (top, marked with circle) was excluded from further studies as it did not show the activity consistently; (b) and (c) examples of fungal strains showing clearing zones on agar plates containing colloidal chitin in minimal medium (b) or chitosan DA 3% in LB medium (c).
