Abstract

Heterosigma akashiwo, which contains large amounts of polyunsaturated fatty acids, might be a natural source of such fatty acids for foods and pharmaceuticals. We studied the effect of culture conditions on the fatty acid composition of this plankton. The total fatty acid content of cells grown at 17°C was 50% (w/w) higher than that of cells grown at 25°C. The fatty acid composition was affected by the culture pH and temperature and by the addition of NaCl. In cells grown at 25°C, C 20:5 accounted for 20% of total fatty acids; in cells grown at 29°C, the proportion was 11% (w/w). The greatest accumulation of C 18:4 was at pH 5.8 with temperature at 17 or 29°C, and the NaCl concentration of 1.6%.
培养条件对赤禾杂交菌脂肪酸组成的影响
赤藻含有大量的多不饱和脂肪酸,可能是食品和药品中这些脂肪酸的天然来源。我们研究了培养条件对这种浮游生物脂肪酸组成的影响。17℃培养的细胞总脂肪酸含量比25℃培养的细胞高50% (w/w)。脂肪酸组成受培养pH、温度和NaCl添加量的影响。在25℃培养的细胞中,C 20:5占总脂肪酸的20%;29℃培养的细胞,比例为11% (w/w)。当pH为5.8、温度为17℃或29℃、NaCl浓度为1.6%时,C 18:4积累量最大。
