Characterization of dextran-producing Leuconostoc strains.
Leuconostoc strains were characterized according to their antibiotic susceptibilities, carbohydrate fermentation profiles, sucrase activity patterns and plasmid content. All the strains tested were resistant to the antibiotics sulphathiazole, trimethoprim and vancomycin, and could be separated into two groups based on whether or not they could ferment melibiose and raffinose. Six Leuconostoc strains possessed plasmids and many produced unique sucrase activity patterns in polyacrylamide gels. These data will aid in distinguishing among physiologically similar dextran-producing leuconostocs, frequently used in research and industry.
