| 摘 要： | 为了提高海洋红酵母发酵虾青素的产量水平,对海洋红酵母的培养基成分进行了初步研究。试验结果表明,海洋红酵母能利用葡萄糖、淀粉水解糖、糖蜜等多种碳源,用淀粉水解糖为碳源培养海洋红酵母所获得的虾青素体积产率最大;用牛肉膏为氮源有利于提高海洋红酵母的生物量,以(NH4)2SO4、NH4Cl和蛋白胨为氮源有利于提高海洋红酵母的虾青素体积产率,用KNO3、草酸铵、蛋白胨、尿素有利于提高海洋红酵母的虾青素细胞产率;在海洋红酵母的培养基中添加Mn2 、Cd2 、Zn2 、Fe2 能增加生物量,添加Zn2 、Fe3 、Mn2 能增加海洋红酵母的虾青素体积产率,添加Fe3 能提高海洋红酵母的虾青素细胞产率。 |

| Abstract: | In order to improve the production level of astaxanthin by oceanic red yeast(ORY),the ingredients of medium for it were studied.The results of experiment showed that ORY could utilize many kinds of carbon sources such as glucose,starch hydrolyzed sugar(SHS),and molasses etc.However,volume productivity of astaxanthin was the biggest among these sugars when using SHS.Using beef extract as nitrogen source is helpful to enhance biomass of ORY, while(NH4)2SO4,NH4Cl and peptone were conducive to improve the ORY volume productivity of astaxanthin.In addition,KNO3,ammonium oxalate,peptone,and urea were conducive to improve the cellular productivity of astaxanthin.Adding Mn2 ,Cd2 ,Zn2 ,and Fe2 to the ORY medium,could increase the biomass.Adding Zn2 ,Fe2 ,and Mn2 could increase the ORY volume productivity of astaxanthin.And adding Fe2 could increase the ORY cellular productivity of the astaxanthin. |
