Red koji rice (Monascus tuber) was fermented to produce lovastatin (Monacolin K, MK). Orthogonal experiment design was employed to determine the optimum high temperature and lasting time, low temperature and lasting time, bottle filling volume and rice charging amount. The opti- mum solid fermentation conditions were: high temperature 35℃ for 5d, low temperature 22~C for 15d, 1L delta bottle with rice charging amount of 360g. Meanwhile, MK and functional Monascus rice display lipid-lowering func...
