sp, has been comprehensively studied for their potential in the production of biodiesel due to their biomass productivity and high lipid content. This study examined the biomass productivity, and concentration, lipid productivity, and concentration, and lipid contents of sp. IFRPD 1061 under several phosphorus concentrations. The optimum conditions were attained at 0.12 g/L KHPO. The highest lipid content reached to 35.950 ± 4.253% (w/w) in 22 days cultivation. An open pond cultivation system was used with the addition of 10 mM sodium acetate on every fourth day (0, 4, 8 and 12) of cultivation and KHPO on twelfth day of cultivation. The obtained biomass productivity and concentration, lipid productivity and concentration and lipid content were 0.709 ± 0.027 g/L, 48.304 ± 1.894 mg/L/day, 0.214 ± 0.004 g/L 14.550 ± 0.215 mg/L/day and 30.154 ± 1.627% (w/w) in 14 days of cultivation, respectively. The results exhibited that addition of 10 mM sodium acetate and KHPO may enhance lipid accumulation within algae cells in an open pond cultivation system.
由于其生物质生产力和高脂质含量，[具体藻类名称]已被全面研究其在生物柴油生产中的潜力。本研究考察了[具体藻类名称]IFRPD 1061在几种磷浓度下的生物质生产力、浓度、脂质生产力、浓度和脂质含量。在0.12 g/L KHPO条件下达到最佳条件。在22天的培养中，最高脂质含量达到35.950±4.253%（w/w）。使用开放式池塘培养系统，在培养的每第四天（0、4、8和12天）添加10 mM乙酸钠，并在培养的第12天添加KHPO。在14天的培养中，获得的生物质生产力和浓度、脂质生产力和浓度以及脂质含量分别为0.709±0.027 g/L、48.304±1.894 mg/L/天、0.214±0.004 g/L、14.550±0.215 mg/L/天和30.154±1.627%（w/w）。结果表明，在开放式池塘培养系统中添加10 mM乙酸钠和KHPO可能会增强藻类细胞内的脂质积累。
