The chitinase was purified to 66 fold having a yield of 17%. The molecular weight of the chitinase was found to be around 29 kDa by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The pH and temperature optima of the purified chitinase were found to be at pH 5.5 and60 ˇăC, respectively. Conclusion, Significance and Impact of the study: Besides showing a significant yield, the enzyme has a highthermal stability which has its applicability in the recycling of chitin waste. %K Chitinase %K S. maltophilia %K Chitin affinity %K Chitinase purification %U http://web.usm.my/mjm/issues/vol9/Research%202.pdf
