The antimicrobial action of chitosan, low molar mass chitosan, and chitooligosaccharides on human colonic bacteria

Original language description

Antibacterial effect of chitooligosaccharides (COS) and low molar mass chitosans (LMWC) is considered as one of the most important characteristics of chitosan (CS) hydrolysates. Here, we show the in vitro effect of different COS, LMWC, and CS on representative anaerobic bacteria isolated from human colon as a possibility of targeting modification of colonic microflora composition by supplementation of dietary CS products by humans. Specific growth rate of seven selected nonpathogenic anaerobic bacterialstrains (Clostridium paraputrificum, Clostridium beijerinckii, Roseburia intestinalis, Bacteroides vulgatus, Bacteriodes thetaiotaomicron, Faecalibacterium prausnitzii and Blautia coccoides) was determined in the presence of 0.25 and 0.5% COS (2, 3, and6 kDa), 0.025 and 0.05% of LMWC (10 and 16 kDa), and 0.025 and 0.1% of CS in vitro. The growth rate decreased in all strains in the presence of COS and LMWC in higher concentrations in comparison to control incubations. A relatively high
