摘要
研究2-脱氧葡萄糖、胡萝卜素、番茄红素等物质对红发夫酵母生长及虾青素合成的影响。番茄红素的添加可以明显提高红发夫酵母细胞内虾青素含量,番茄红素的添加量为700μg/L时,虾青素含量与产量均达到最高,分别为1468μg/g、17.59 mg/L,对照空白分别提高了72%、69%。结果表明番茄红素适量添加对虾青素合成起到促进作用,但成本较高,由于番茄汁富含番茄红素并且成本较低,可以作为替代品进行流加,节约成本。
2-deoxyglucose, carrot juice and tomato juice have great effect on the growth of Phaffia rhodozyma and astaxanthin production. Adding lycopene can promote the astaxanthin content siginificantly. However, it is not propitious to the growth of P. rhodozyma. When lycopene of 700 μg/L was added, astaxanthin content was increased 72% and astaxanthin production was increased 69%. The result showed that lycopene was the better additional matter. However, it is very expensive. Tomato juice, which is very cheap, contains much lycopene. Therefore, it was a good substitute.
