Renewable energy produced by microalgae has been recently considered as one of the most important resources to replace the use of petroleum-based fuels. Microalgae have many advantages as promising alternative energy sources due to their higher photosynthetic efficiency, rapid growth rate and the ability to accumulate a high amount of lipids to crop-based biomass and lignocellulosic biomass. Despite of many advantages of microalgae as energy resources, however, several barriers still need to be overcome. Especially, low biomass productivity has been a critical limitation for development of microalgae based fuel production technology. To supply stable biomass for downstream processes, we performed phototrophic cultivation with Chlorella sp. HS2 which was isolated from wastewater. Our results revealed the effects of variable light intensities on growth. These results highlight the potential of Chlorella sp. HS2 as a suitable candidate for fulfilling the high productivity under phototrophic condition. Now we are in the process of optimizing light intensities in order to maximize biomass productivity for microalgae cultivation. |
