Effects of an alginate oligosaccharide mixture (AOM) on Nannochloropsis oculata, a unicellular marine microalga, were investigated. The growth of N. oculata was significantly promoted by AOM in a concentration-dependent manner. The maximum effect was attained at 20 mg/ml, at which the growth rate of the alga became nearly 5 times higher than that of control without AOM. The growth-promoting effect of AOM decreased slightly at 40 mg/ml. Furthermore, the algicidal effect of Cu(2+) was profoundly alleviated by the addition of AOM. These results suggest that AOM is useful for promoting and/or improving the growth of N. oculata.
研究了海藻酸钠寡糖混合物（AOM）对单细胞海洋微藻眼点拟微球藻的影响。AOM以浓度依赖的方式显著促进了眼点拟微球藻的生长。在20mg/ml时达到最大效果，此时藻类的生长速率比无AOM的对照组高出近5倍。在40mg/ml时，AOM的促生长作用略有下降。此外，添加AOM可显著减轻Cu(2+)的杀藻作用。这些结果表明，AOM可用于促进和/或改善眼点拟微球藻的生长。
