摘要: 目的 弄清红曲霉菌的一些生理学特性。方法 以土曲霉为对照,对常见几种用于发酵制备红曲用的红曲霉进行了9种氮源、13种碳源利用及明胶水解等生理学特性试验。结果 所有红曲霉均能利用大豆粉等有机态氮,对硫酸铵等无机态氮的利用则有明显差异;大多数红曲霉均能利用大部分糖类,但均不利用乳糖醛酸,对棉子糖、乳糖、鼠李糖及山梨糖等少数糖类的利用表现出明显差异;变红红曲霉和紫红曲霉能使明胶水解,其余则不能水解明胶。结论 氮源、碳源利用及明胶水解反应作为对红曲霉分类的生化指标,具有一定的价值。Abstract: OBJECTIVE Study on the physiological characteristics of Monascus fungi.METHODS Control as Aspergillus terreus ,the 7 ordinary species of Monascus including M.aurantiacus Lee,et al were tested with 9 kinds of sources of nitrogen and 13 kinds of sources of carbon and the abilities of hydrolysis of gelatin.RESULTS All of the tested Monascus can utilize organic nitrogen such as soybean flour,while exist obviously differences in using inorganic nitrogen such as ammonium sulfate.The tested Monascus can utilize most of carbohydrates,while not utilize lactobionic acid.There exist obviously differences in using gossypose,lactose,rhamnose and sorboae. M.serorubesceus Sato and M.purpureus Went can hydrolyze gelatin while others not.CONCLUSION There are valuable of nitrogen and carbon utilization and the abilities of hydrolyzing gelatin to the identification of Monascus fungi.
