Zusammenfassung: | BACKGROUND: This study addressed the characteristics of metabolites synthesized by Lactobacillus acidophilus 5e2, with particular attention paid to exopolysaccharides, biosurfactants, proline peptidases and antibacterial compounds.RESULTS: The strain Lb. acidophilus 5e2 synthesizes low-molecular-mass polysaccharides (340 kDa) constituted by glucose, galactose and glucosamine at a ratio of 3.3:2.8:1.0, as well as biosurfactants with a molecular mass of 32 kDa built from a protein fraction, a polysaccharide fraction and phosphate groups. It additionally synthesizes extra- and intracellular proline peptidases, including prolyl endopeptidase and thermostable low-molecular-mass ( |
