Abstract
Chitinase production by Serratia marcescens 990E was maximal (34 U/ml) for a dissolved oxygen concentration ranging from 20 to 50% saturatio n. Chitin addition (6 g/l) at the end of fermentation reactivated the growth but did not bring about further chitinase accumulation. Four ch itinases with different isoelectric points were separated.
