Swollen chitin, flake chitin, powder chitin, and mushroom paste were used as substrates for chitinase production by Serratia marcescens GG5 in submerged fermentation. Enzyme production was 0.3 U/ml when the organism was grown in M9 medium supplemented with 0.5% swollen chitin and 0.5% soluble starch. Scanning electron microscopy revealed that Serratia marcescens GG5 digested the chitin flakes by producing chitinase.
