Fluorochemical as an oxygen carrier for the growth of microalgae for biodiesel production

The microalgae cultured with the aid of PFCs for algal cell culture presented here, PFCs were used to supply carbon dioxide for cell growth and sweep out oxygen, which is considered as an inhibitor for algal growth. The results indicate that cultivation of the microalgae on the inter phase between liquid growth medium and PFC liquids increases cell growth rates and biomass in a variety of carbon dioxide concentrations ranging from 2 to 20%. The use of per fluorocarbon also caused remarkable increases in both glucose and oxygen consumption rates. The implication of this novel culture method can be harnessed to develop environmentally friendly technology for sequestering carbon dioxide by massive biomass growth of microalgae. By utilizing a fluorochemical, the free oxygen will be removed by degradation; it also helps in increasing photosynthesis which will provide a greater amount of biomass.
