摘要:
本文研究了有机碳源和无机碳源对球胞鱼腥藻生长的影响, 结果表明:有机碳源中葡萄糖以0.5—1.0μg/mL、蔗糖以5.0μg/mL促进其生长效果最好;无机碳源中, 碳酸钠以10.0—15.0μg/mL、碳酸氢钠以10.0μg/mL效果最好。葡萄糖和蔗糖的浓度高低对球孢鱼腥藻叶绿素a的含量没有明显影响, 但前者略高于后者。碳酸钠和碳酸氢钠的浓度在5.0μg/mL时均提高了叶绿素a含量。四种碳源都提高了球孢鱼腥藻的同氮活性, 有机碳源中蔗糖优于葡萄塘, 无机碳源中碳酸钠优于碳酸氢钠。

Abstract:
The effects of organic and inorganic sources on the growth of Anabaena syhaaerica HB 1017 are studied. The result shows that in organic carbon sources,the most effective concentrations of glucose and sucrose are 0. 5-1. 0 pg/mL and 5. 0 pg/mL respectively;while in the inorganic carbon soureces,the most effective concentrations of sodium carbonat and bicarbonat are 10. 0-15. 0 pg/mL and 10. Oug/mL respectively. The concentration of glucose or sucrose have no influence on the chlorophyll., but A. sphaerica HB 1017 bit a little more chlorophyll a when cultured in medium containing glucose than in containing suerose. Both sourcess carbonate of the four carbon and bicarbonate raise chlorophyll_a at the concentration of 5. 0 pg/mL. All sources can in the organic carbon sources enhance the nitrogen-fixing ability of A. sphaeria HB 1017,but sucrose has greater effect than glucose;while in the inorganic carbon sources,the effect of sodium carbonate is greater than that of sodium bicarbonate.
