摘　　要：丝状真菌利用光源并不是单纯的作为能源而是作为信息的来源,对真菌的生长发育及次级代谢有重要的调控作用。本研究通过菌落观察、色价测定及分生孢子和闭囊壳的计数方法发现,黑暗条件下Monascus ankaGZU4577菌落较大,促进菌株的营养生长;而且黑暗条件下Monascus anka GZU4577菌株的色素积累,分生孢子数量以及闭囊壳的数量明显大于光照条件。实验证实相比于白光条件,黑暗条件更有利于Monascus anka GZU4577的生长发育以及色素的积累。推测红曲霉可能存在不同的光反应调控系统,为后续红曲霉光调控研究奠定基础。Different from plants, fungi use light not only as a source of energy but as a source of information. Accordingly, light plays important roles in fungi growth and the regulation and the control of secondary metabolism. In this study, through the observation of Monascus shape, the measurement of color value, and the counting of spore and cleistothecia, it was found that dark could enhance the formation of cleistothecium as well as conidia and mycelia in Monascus anka GZU4577and dark could stimulate the production of pigments in Monascus anka GZU4577. It was then concluded that dark, compared with light, was good for the growth of Monascus anka GZU4577 and the accumulation of pigment. These findings suggested that different light regulation system might exist in Monascus. This study had laid foundation for consequent research on light regulation and control of Monascus.
