Characteristics of the Leuconostoc mesenteroides subsp. mesenteroides strains from fresh vegetables

Strains synthesizing extracellular polysaccharide dextran on a medium with 10% sucrose were isolated from different kind of vegetables (cabbage, cucumber, cauliflower, kohlrabi, carrot, green beans, red beet, pepper, eggplant, radish). Carbohydrate fermentation was examined using a bioMerieux API 50 CHL test system. Among micropopulations with characteristic spherical cell morphology, 94.9% belonged to Leuconostoc mesenteroides subsp. mesenteroides and 5.1% were identified as Leuconostoc mesenteroides subsp. dextranicum. According to fermentation of pentoses L. mesenteroides strains were divided into three groups with a certain number of biotypes; 10 strains were tested on acid production..
