【摘要】 在含 2 5mg·L- 1 的亚甲基兰的正常和无氮培养液中培养盐泽螺旋藻 ,观测盐泽螺旋藻的生长、叶绿素含量、藻胆素含量及其对亚甲基兰的脱色率。结果表明 ,盐泽螺旋藻可由染料亚甲基兰提供唯一氮源 ,但不能提供唯一碳源。在培养 8d后 ,无氮培养液中的螺旋藻液吸光度达到 0 2 1 0 ;在正常培养液下螺旋藻液吸光度为 0 32 1。盐泽螺旋藻对染料的脱色效果也比较好 ,在培养 8d后 ,无氮培养液下亚甲基兰脱色率为 85 %;正常培养液下亚甲基兰脱色率为 86%。更多还原

【Abstract】 Culturing Spirulina subsalsa in normal and non N nutrient fluid including methylene blue(2.5 mg·L -1 ) was studied.Growth curve,the content of chlorophyll, the content of phycobilin, discolorizing efficiency of methylene blue were measured. The results showed that Spirulina subsalsa could use methylene blue dye as only N resource for its growth. After 8 days, absorptivity of the cultured solution was 0 210 in non N nutrient fluid and 0 321 in normal nutrient fluid. In addition, after 8 days, the discolorizing efficiency of methylene blue is 85% in non N nutrient fluid and 86% in normal nutrient fluid.更多还原
