A commercial lipolytic preparation ofChromobacterium viscosum has been separated by gel filtration on a sephacryl 200 HR column. Two lipolytic active fractions were obtained. PAGE, SDS-PAGE and IEF analysis were performed on both the mixture and the two lipolytic fractions. The results do not completely agree with those reported in the literature, suggesting that the high molecular weight lipase is probably an aggregate of lipases contained in the low molecular weight peak.
