以谷氨酸为氮源，设计了一种化学成分确定的培养基，用于培养两种Monoclonal（M。ruber和M. purpureus），导致它们的颜料的最佳生产，并且比较它们的化学结构（游离的和络合的）。用红外光谱、紫外光谱、核磁共振谱和质谱等方法测定了两种主要的复合色素在水溶液中的结构。它们是以氨基取代吡咯烷酮氧原子与谷氨酸连接的游离色素。
A chemically defined medium with glutamic acid as nitrogen source was devised for the culture of two species of Monascus (M. ruber and M. purpureus), resulting in optimum production of their pigments and their chemical structures (both free and complexed) were compared. Structural data on two major complex pigments in aqueous solution were obtained by IR, UV, NMR and MS, They were free pigments linked to glutamic acid by amino groups, where nitrogen replaced the pyronoid oxygen.
