亚硫酸氢钠对鱼腥藻生长的影响

EFFECT OF NaHSO3 ON THE GROWTH OF ANABAENA

摘要: 在不同条件下研究了光呼吸抑制剂——亚硫酸氢钠对鱼腥藻(Anabaena)生长的影响。结果表明亚硫酸氢钠的浓度在1—10μg/ml时都提高了鱼腥藻的生物量,浓度在2.5和5.0μg/ml的效果优于其他浓度。亚硫酸氢钠提高了鱼腥藻叶绿素a的含量,但是,对蛋白质的含量没有的影响。亚硫酸氢钠用于增加鱼腥藻生物产量是有意义的。

Abstract: The effct of NaHSO3, a photorespiratory inhibitor, on the growth of Anabaena was studied in the laboratory and field. NaHSO3 at concentrations of 1—10μg/ml enhanced the biomass production of the algae. Best results were achieved at concentrations of 2.5 and 5.0μg/ml. NaHSO3 increased the content of chlorophyll a in the algae, but not the content of protein.
