The wild type (Monascus kaoliang KB9)
a red mutant (KB10M16), a yellow mutant
(KB20M10.2) and a white mutant (KB20M1) were
maintained in MYS agar (Yongsmith et al., 1990;
Yongsmith et al., 1994). The solid-culture media
used for the study on the culture characteristics
were MYS, GYP, and Potato Dextrose Agar
(PDA). The GYP medium was composed of 4%
