Abstract

Two Korean strains of Akashiwo sanguinea (LMBE-V203 and LMBE-V287) were established, and their morphologies and molecular phylogenies were examined. In addition, the effects of combined temperature and salinity on their growth and fatty acid contents were examined to evaluate the value as potential source for commercial application. Morphological observations indicated that there were no critical differences in the morphologies of both isolates, and molecular phylogeny based on LSU rRNA gene sequences revealed that the two isolates are nested within ribotype A of A. sanguinea. The two isolates exhibited different growth responses to combined temperature and salinity conditions, because of possibly the differences in sampling locations characterized by of different environmental conditions. At the optimal temperature and salinity, the maximum cell concentration was approximately three times higher in culture of LMBE-V287 than in culture of LMBE-V203, and the growth rate in the culture of LMBE-V287 was also higher than that in the culture of LMBE-V203. The optimal conditions to maximize biomass for batch cultures of Korean isolates of A. sanguinea (ribotype A) were a temperature of 20 °C and a salinity of 35. Cultures of two isolates had similar fatty acid compositions, and both isolates had a moderate content of EPA plus DHA, compared to other microalgal species. Therefore, the two Korean isolates of A. sanguinea (ribotype A) can be candidates for the commercial production of EPA plus DHA. There were differences in the fatty acid contents between the cultures of two isolates exposed to combined temperature and salinity conditions. The monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) of LMBE-V203 at the same salinity increased with decreasing temperature and the saturated fatty acids (SFAs) under same salinity level increased with increasing temperature, whereas no clear tendency for the SFAs and PUFAs of LMBE-V287 was found. This result indicates that the MUFAs and PUFAs of strain LMBE-V203 can be modulated by controlling temperature.

摘要

建立了两株韩国血红哈卡藻（LMBE-V203和LMBE-V287），并对其形态和分子系统发育进行了研究。此外，研究了温度和盐度组合对其生长和脂肪酸含量的影响，以评估其作为商业应用潜在来源的价值。形态学观察表明，两种分离株的形态没有显著差异，基于LSU rRNA基因序列的分子系统发育分析表明，这两种分离株嵌套在血红哈卡藻的核糖体A型中。由于采样地点的环境条件不同，这两种分离株对温度和盐度组合条件表现出不同的生长反应。在最佳温度和盐度下，LMBE-V287培养物中的最大细胞浓度比LMBE-V203培养物中的高约三倍，LMBE-V287培养物中的生长速率也高于LMBE-V203培养物中的生长速率。韩国血红哈卡藻（核糖体A型）分批培养中使生物量最大化的最佳条件是温度20℃和盐度35。两种分离株的培养物具有相似的脂肪酸组成，与其他微藻物种相比，两种分离株的EPA加DHA含量适中。因此，这两株韩国血红哈卡藻（核糖体A型）可作为商业生产EPA加DHA的候选藻种。在温度和盐度组合条件下，两种分离株培养物的脂肪酸含量存在差异。在相同盐度下，LMBE-V203的单不饱和脂肪酸（MUFAs）和多不饱和脂肪酸（PUFAs）随温度降低而增加，饱和脂肪酸（SFAs）在相同盐度水平下随温度升高而增加，而LMBE-V287的SFAs和PUFAs没有明显趋势。这一结果表明，菌株LMBE-V203的MUFAs和PUFAs可通过控制温度来调节。
