Abstract:

?以多形拟绿球藻(pseudochlorococcumpolymorphumutex1791)和模式拟绿球藻(pseudochlorococcumtypicumutex1792)为材料,采用bg-11培养基,研究其在0.3、0.5、1.0和1.5g·l-1等4个硝酸钠浓度条件下的生长和总脂含量。结果表明:适宜多形拟绿球藻生长的硝酸钠浓度范围为0.3?1.0g·l-1,其最终生物质干重在3.7g·l-1左右;模式拟绿球藻在1.0g·l-1的硝酸钠浓度条件下生长最好,可获得4.35g·l-1的生物质干重。在培养过程中两株绿藻的叶绿素a含量与总脂的含量关系密切,在培养初期各实验组叶绿素a含量增加,藻体的总脂含量增长不明显,而在培养中期藻细胞叶绿素a的含量增长平缓,总脂含量增长较明显,其中在0.3g·l-1的硝酸钠浓度实验组总脂增长最为显著,多形拟绿球藻增长了11.65%,模式拟绿球藻增长了24.99%。两株绿藻在0.3g·l-1的低氮实验组总脂含量最高,多形拟绿球藻和模式拟绿球藻总脂分别为细胞干重的44.35%和26.28%,在此条件下两株藻的最大总脂收获量分别为0.98g·l-1和1.61g·l-1。
