Abstract
Growth of 6 bacterial strains representing dominant members of the human colonic microflora was measured in the presence of 0.025, 0.05 and 0.5 % chitosan (from shrimp shells, with a 97 % final degree of deacetylation). The effect of chitosan was variable and dependent on bacterial species. The most susceptible to chitosan were bacteria belonging to generaBacteroides andClostridium (91–97% growth inhibition). On the other hand,Roseburia sp.,Eubacterium sp. andFaecalibacterium sp. were more resistant (63–83 % inhibition of growth). Chitosan can thus be considered as one of the means for influencing the bacterial population in the human colon.
