Four green microalgae (TRG, KB, SK, and PSU) identified as Botryococcus spp. by morphological criteria were isolated from lakes and freshwater ponds in southern Thailand. In nitrogen-rich medium the strains achieved a lipid content of 25.8%, 17.8%, 15.8% and 5.7%, respectively. A combination of nitrogen deficiency, moderately high light intensity (82.5 μE m(-2) s(-1)) and high level of iron (0.74 mM) improved lipid accumulation in TRG, KB, SK, and PSU strains up to 35.9%, 30.2%, 28.4% and 14.7%, respectively. The lipid contents and plant oil-like fatty acid composition of the microalgae suggested their potential as biodiesel feedstock.
从泰国南部的湖泊和淡水池塘中分离到四种绿藻（TRG、KB、SK 和 PSU），根据形态学标准将其鉴定为 Botryococcus 属。在富氮培养基中，这些菌株的脂质含量分别达到 25.8%、17.8%、15.8%和 5.7%。氮缺乏、适度高光强（82.5 μE m(-2) s(-1))和高铁水平（0.74 mM）的组合使 TRG、KB、SK 和 PSU 菌株的脂质积累分别提高到 35.9%、30.2%、28.4%和 14.7%。微藻的脂质含量和植物油脂样脂肪酸组成表明它们有作为生物柴油原料的潜力。
