Abstract/OtherAbstract:
A yeast, Rhodotorula glutinis, is regarded as a potential microbial oil producer, due to its high lipid content. The flask results of this study indicated that irradiation could increase the growth of R. glutinis compared to that of a batch without irradiation. Further 5-l fermenter results confirmed that irradiation could greatly enhance the cells' growth rate and total lipid productivity. The maximum lipid productivity obtained in the fed-batch operation with 3 LED (light emitting diode) lamps was 0.39g/lh as compared to 0.34g/lh in the batch with 3 LED lamps and 0.19g/lh in the batch without irradiation. Conclusively, the irradiation could significantly increase the cells' growth rate, which, in turn, could be applied to the commercialized production of biodiesel from single cell oils.
