Abstract
The exopolysaccharides produced by three propionibacteria strains, Propionibacterium freudenreichii 109, Propionibacterium freudenreichii 111, and Propionibacterium thoenii 126, grown on whey-based media, were found to be charged heteropolymers, composed of d-glucose, d-mannose, and d-glucuronic acid in molar ratios of 2:2:1. By means of methylation analysis, mass spectrometry, partial acid hydrolysis, and 1D/2D NMR (1H and 13C) studies, it was determined that all three exopolysaccharides contain the same branched, pentasaccharide repeating unit: Figure optionsDownload full-size imageDownload as PowerPoint slide
