- Abstract
The microbiological and technological characterization of Leuconostoc mesenteroïdes species isolated from raw goat milk, camel milk and Roquefort cheese identified nine strains of Ln. mesenteroïdes subsp. mesenteroïdes and nine strains of Ln. mesenteroïdes subsp. dextranicum. The results of technological tests of the strains showed that strains produced dextran, carbon dioxide, and resist to 55° C for 15 minutes, which promote their industrial use. The growth kinetic, acidification and carbon dioxide production of Ln. mesenteroïdes subsp. dextranicum strain in skim milk at 30°C were slightly higher than Ln. mesenteroïdes subsp. mesenteroïdes. Yeast extract addition to skimmed milk stimulates the development of Ln. mesenteroïdes subsp. mesenteroïdes by increasing its growth, acidification activity and evolved CO2. Susceptibility to antibiotics was evaluated on 33 antibiotics and strains of Leuconostoc mesenteroïdes showed resistance to 42,4% of antibiotics used.
