Antibacterial activities
A series of tubes with average liquid that contains
variable and well-known concentrations of
the chitooligosaccharide and its derivative were
prepared. Thereafter, each tube was inoculate with
the microorganism and incubated at 37 ∞C for
18 h. The presence or absence of the development
of microorganisms indicates the bacterial sensitivity
to the compound tested. The lowest concentration
that completely inhibits the bacterial growth
