Heterotrophic medium optimization by Chlorella sp. HS2 with using modified BG11 |
| 초록 |
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. Despite of many advantages of microalgae as energy resources, however, several barriers still need to be overcome[1]. Especially, low biomass productivity has been a critical limitation for scale-up of microalgae based fuel production technology. To supply stable biomass for downstream processes, we performed heterotrophic cultivation with Chlorella sp. HS2 that was isolated from wastewater. To develop the process technology in microalgal cultivation, single-factor experiment was applied to optimize the cultivation conditions. Our results revealed that biomass productivity of Chlorella sp. HS2 grown under heterotrophic condition is much higher than cells grown under photoautotrophic condition. Now we are in the process of optimizing various conditions in order to maximize biomass productivity under heterotrophic condition. |
