Abstract: The Monascus was separated from the red furu(fermented bean curd) made in China with medium of malt wortdepending on the trait of Monascus growth . The agar medium of malt wort , rice medium , the medium of soybean sprout extractand the fermented medium were used respectively to purify strain of the separated Monascus. It showed the good effect of purityfor the rice medium . The experiment showed that Monascus was a kind of mold with anti-acid and anti-alcohol properties. Thecolony of Monascus revealed shape round on the agar medium of malt wort , and started growth at 32℃ for 48 hours. The colonycolour became from white, light-pink, and red to purple, and the all colony of Monascus showed purple colour after 12 days. Withobservation of microbioscope the hypha of Monascus had no separation membrane, but with multi nuclei and multi branch, whilesporodochium sited the hypha top,with mono-sporodochium or a chain of sporodochium and a round cleistothecium.

Key words: Monascus, separation, pure medium, trait of Monascus morphology
