Abstract
Red, orange and yellow pigments are produced by Monu~clrf~un gi duFing fmnmmtion in mghk p-r hdw d i m showed that it also produced other metabolites whrch have antimicrobial activiry. The Wuence of the kq# of -*on time of angkak extract on the redness and antimicrobial a&* agdnst mbf& has BardBardLbadg. & ~RU ~ ~ ~-ref !:4t.T%c~&mitrad~~bzietwrrev~apolandodingv8crrmo~~ary mapabr mt SO%, 50 nabat at d-1 l m s of ewpdsathn rime i.e. 15.30,45,60 d 75 minures.
