The best production of anti-cholesterol
agent in the study occurred with the red wild-type
KB9 although it was slow during the first and
second weeks of incubation, yielding only 1,701-
5,724 mg/kg. After that, the productivity increased
to 9,079-17,892 mg/kg in the later phase during
the third and fifth weeks of incubation. The anticholesterol
agent production was related to
pigment production in the KB9 strain at week 4
and 5.
