Abstract
Numeric taxonomy analysis of 70 lactic acid bacteria (LAB) and 30 Enterobacteriaceae from lightly salted lumpfish roe, showed that Enterobacteriaceae formed three subgroups: Morganella morganii presumptive Serratia liquefaciens and Serratia plymuthica. LAB formed three subgroups of presumptive Lactococcus spp. and Carnobacterium spp. Production of off-odors and volatile sulfur compounds by twelve selected strains and three Vibrio spp. of identical origin in pasteurized roe, and of three Enterobacteriaceae in sterile fresh roe, was examined. Morganella morganii produced off-odors and volatile sulfur compounds in both pasteurized and fresh roe. One Serratia liquefaciens produced strong off-odors but no volatile sulfur compounds in fresh roe.
