Abstract

In this study, the effects of salt and nitrogen were investigated on lipid and carbohydrate production in marine microalgae Dunaliella tertiolecta. All the experiments were performed in dark. Low salinity (3.7 PSU) was most suitable for lipid content (39%) and lipid productivity (100.584 mg/L/d). The maximum carbohydrate content (59.4%) and carbohydrate productivity (65.23 mg/L/d) were achieved in the absince of salinity. During nitrogen ( NaNO₃) stress, the lipid and carbohydrate contents increased to 38.4% and 53.14% from 28% and 45%, respectively. However, interestingly, the effect of nitrogen stress on lipid and carbohydrate productivities was not significant.

摘要

在这项研究中，研究了盐和氮对海洋微藻Dunaliella tertiolecta中脂质和碳水化合物产生的影响。所有实验均在黑暗中进行。低盐度 (3.7 PSU) 最适合脂质含量 (39%) 和脂质生产力 (100.584 mg/L/d)。在没有盐度的情况下实现了最大碳水化合物含量（59.4%）和碳水化合物生产率（65.23 mg/L/d）。在氮（NaNO ₃）胁迫下，脂质和碳水化合物含量分别从28%和45%增加到38.4%和53.14%。然而，有趣的是，氮胁迫对脂质和碳水化合物生产力的影响并不显着。
