摘要：

Microbial fermentation of citrinin-free Monascus pigments is in favor in the development of food industry. This study investigated the influences of carbon source, nitrogen source, and mineral salts on the cell growth, monascin (MS), and citrinin (CT) production in Monascus M9. A culture medium composition was established for maximizing the production of citrinin-free MS in submerged culture, as follows: 50g/L Japonica rice powder, 20g/L NH4NO3, 3g/L NaNO3, 1.5g/L KH2PO4, 1g/L MgSO(4)7H(2)O, 0.2g/L MnSO4. Under these conditions, no CT was detectable by high performance liquid chromatography. The yield of MS reached 14.11mg/g, improving approximately 30% compared with before optimization.
