ABSTRACT
Xylan was found to stimulate the growth of a population of Anoplodinium denticulatum when
supplied at a rate of 0.03 and 0.06 mg/ml culture/d. The protozoa were able to digest xylan since the
crude enzyme preparation from the cells of ciliates incubated with this polysaccharide released over
811 μM xylose/mg protein/h. An increase in the VFA concentration followed the incubation of ciliates
with xylan in the presence of antibiotics with the main fermentation products being acetic and butyric
acids. The production rate of total VFA was 6.4 pM/protozoan/h.
