Prebiotic potential of chitosan and chitooliosaccharides
Original language description
Chitosan (CS) is a natural nontoxic biopolymer derived by deacetylation of chitin, a major component of the shells of crustacea such as crab. Chitosan and chitosan oligomers (COS) have variously biological activities and one of commercial applications isin food com-plements. The most important function of chitosan is considered its antimicrobial activity. The aim of this study is to investigate in vitro effect of different chitosan and its derivates on beneficial bacterial strains from human colon. Thecrude fractions of COS/CS were prepared by enzymatic hydrolysis of chitosan. Grow rate of bacterial strain was measured in the presence of 0.025; 0.05 and 0.5 % COS/CS in anaerobic medium M10 and TPY medium. The effect of chitosan products was variableand dependent on concentration and molecular weight of COS/CS and also on bacterial species. COS did not show any inhibitory effect against bifidobacterial strain. In some case was observed increased growth rate.
