Mixotrophic Cultivation of Synechocystis sp@6803:Influences of Light Intensity and Glucose
集胞藻6803的混合培养——光照强度和葡萄糖的影响

The growth characteristics and the effects of glucose and light on the growth of Synechocystis sp. PCC6803 under mixotrophic conditions have been investigated. An exponential growth phase had been observed before glucose was consumed. The results showed that both of light intensity and glucose concentration had obvious effects on the mixotrophic growth of Synechocystis sp. PCC6803: the specific growth are decreased with the increase of glucose concentration at light; the specific growth rate and biomass/glucose yield increased with light intensity, ranging from 15-55 microE.m-2.s-1; when light intensity was higher than 55 microE.m-2.s-1, light saturation appeared.
