In a first aspect, the present invention relates to a method for isolating
cell wall derivatives from fungal or yeast biomass. According to this
method, chitin polymers or chitin-glucan copolymers can be obtained. In
another aspect, the invention relates to a method for preparing chitosan
from chitin. The invention further relates to chitin polymers,
chitin-glucan polymers and chitosan polymers obtainable by the methods
according to the invention. Moreover, the invention relates to the use of
chitin polymers, chitin-glucan copolymers or chitosan polymers obtainable
by the method according to the present invention in medical,
pharmaceutical, agricultural, nutraceutical, food, textile, cosmetic,
industrial and/or environmental applications.
