光合细菌G3菌株固定化保存方法的研究

摘要

[ Objetive ] The aim was to study a new and effective method for the preservation of Photosynthetic Bacteria. [ Method]With AIK (SO4)2 · 12H2O as coagulant, trehalose as protective agent and ceramic powder as fixative, the Photosynthetic Bacteria G3 were immobilized at room temperature,4 ℃ and -20 ℃ respectively. After 30 days,the effective number of live bacteria was determined and the growth conditions of Photosynthetic Bacteria were observed. [ Result ]The results showed that the growth and activity of immobilized Photosynthetic Bacteria were exuberant. [ Conclusion ] The immobilized method provided a new and effective method for the preservation of Photosynthetic Bacteria.%[目的]研究一种新的有效的光合细菌菌种保藏方法.[方法]以硫酸铝钾作絮凝剂,海藻糖作保护剂,陶瓷粉作固定剂,分别在常温,4、-20 ℃下保存光合细菌G3菌株,30 d后测定有效活菌数并观察生长情况.[结果]固定化保存的光合细菌活性较好,生长繁殖旺盛.[结论]固定化方法为光合细菌工业化生产的菌种保藏提供了一种新的有效方法.
