【摘要】 在用环形培养池模拟系统培养雨生红球藻的过程中,研究了温度对雨生红球藻生物量及虾青素产量的影响。结果表明,在15～25℃的范围内,不同温度下雨生红球藻生物量和虾青素含量及产量都经历了一个上升—最高—下降的过程。25℃与22℃时红球藻的虾青素产量、虾青素含量(干重)均显著高于其他温度的(P<0.01),但两者间差异不显著(P>0.05)。15℃时,红球藻生物量、虾青素含量和虾青素产量均最低,分别为1.4g、0.54%和2.49mg/L;25℃时,红球藻生物量和虾青素产量最高,分别为2.68g和13.53mg/L;22℃时,虾青素含量最高,为1.52%。更多还原

【Abstract】 The effects of temperature on the biomass, astaxanthin yield and astaxanthin content of Haematococcus pluvialis cultured in imitation system of circular pond has been investigated. Results showed that the biomass, content of astaxanthin and astaxanthin yield of H. pluvialis all experienced a trend of increase-highest-decrease in the range of 15℃-25℃. The astaxanthin yield and astaxanthin content (DW) at 25℃ and 22℃ were significantly higher than the others and with no significant difference between them. The biomass and astaxanthin yield reached their minimum at 15℃, were 1.4 g, 2.49 mg/L, respectively, and reached their maximum at 25℃, were 2.68 g, 13.53 mg/L, respectively. While astaxanthin content reached its minimum at 15℃, was 0.54% and reached its maximum at 22℃, was 1.52%.更多还原
