CO_2浓度对光生物反应器高效培养的湛江叉鞭金藻和盐藻的影响

吴垠;孙建明;孙培海;张德明

  The effects of CO_2 concentration on the growth and photosynthesis of Dicrateria zhangjiangensis and Dunaliella sp.in 100 liter air lift photobioreactors were investigated. The results showed that biomass of both algae significantly increased in high CO_2 concentration (above 700μL·L~(-1) ) compared to low CO_2 concentration(350μL·L~(-1)),and the culture periods were shorter. However, no significant difference as observed in growth rate when the alga cultured in CO_2 concentration of 700μL·L~(-1) and 1000μL·L~(-1), respectively. These for the maximum photosynthetic rate(Pm) and saturating irradiance level(Ik) of the two species remarkably raised with the elevated CO_2 concentration, so was the initial slope(α)of Dunaliella sp.……
