摘    要:研究雨生红球藻混合营养生长与异养生长对碳源及碳源浓度的需求,并对两种生长型进行比较。结果表明,乙酸钠较葡萄糖等碳源更能维持红球藻进行混合营养民异养生长。红球藻混合营养型生长与异养型生长的适宜乙酸钠浓度范围分别是0.5 ̄1.0g/L和1 ̄1.5g/L。混合营养型及异养型的平均速率分别是0.72d^-1和0.53d^-1,培养8d的细胞干重分别是0.65g/L和0.32g/L。与光养型(对照)相比,混

Abstract:Mixotrophic and heterotrophic growth of Haematococcus pluvialis and the request of carbon resource were investigated. The microalga grew better on acetate than glucose and other carbons in both growth modes. The optimum growth concentration of acetate in mixotrophic and heterophic were 0.5- l.0g / L and l.0-l.5g/ L respectively. The average growth rates of Anxotrophjc and heterophic were 0.72d~-1 and 0.53d-1 respectively. After cultured for 8 days, the cell dry weight of mixotrophic and heterotrophic were 0.65g / L and 0.32g / L respectively. Compared with phototrophic (control), the average growth rate and cell dry weight of mixotrophic increased, but in heterotrophic, they decreased.
Keywords:Haematococcus pluvialis   Mixotrophic   Hetertrophic   Carbon resource
