The biological activity of chitosan oligomers of various molecular masses was examined on E.coli (АТСС 25922), S.aureus (АТСС 25923), and fungus Candida albicans (АТСС 10231). All the samples under study inhibited the growth of these microorganisms, especially S.aureus. The dependence of the biological activity of chitosan oligomers on their concentration, exposure time, and molecular mass has been established.
