Chitooligosaccharides were prepared through the hydrolysis of chitosan with α -amylase. Escherichia coli, Staphylococcus aureus and Lactobacillus acidophilus were used as experimental microorganisms. The effect of sodium selenite on microorganism growth in the presence of various concentrations of chitooligosaccharides was investigated by microcalorimetric and turbidity methods. Results indicated that the inhibitory effect of sodium selenite on microorganism growth exhibited an obvious decrease with increasing chitooligosaccharides concentration.

Key words: chitooligosaccharide, sodium selenite, microorganism
