本研究では、マイクロ波照射による微細藻類Scenedesmus spの脂質、多糖類、バイオマスの産生を改善することに焦点を当てた。バイオマスと脂質含量の同時改善により、総脂質産生量は0.76(マイクロ波未処理)から1.42g/L(マイクロ波処理)に改善された(12日培養細胞)。また、バイオマスと脂質含量では、マイクロ波処理によりExopolysaccharides (EPS)の産生量が最大2.3倍に向上した。さらに、マイクロ波処理により、バイオディーゼルの特性がある程度改善された。マイクロ波照射は、微細藻類の総脂質生産量を向上させるための有望な物理処理法である。
The present study focuses on the use of microwave irradiation to improve the production of lipid, exopolysaccharide and biomass in the microalgae Scenedesmus sp. Microwave treatment conditions such as microwave power, duty cycle % and time was optimized to increase the biomass and lipid content of Scenedesmus sp. Microwave power 100 W, duty cycle 40 %, and 2 min treatment time led to a substantial improvement in the biomass and lipid content. Due to the simultaneous improvement in both the biomass and lipid content, the total lipid production was improved from 0.76 (microwave untreated) to 1.42 g/L (microwave treated) (12 days grown cells). In addition, with biomass and lipid content, microwave treatment also enhanced the production of Exopolysaccharides (EPS) up to 2.3-folds. Furthermore, biodiesel properties were improved to some extent after the microwave treatment. Microwave irradiation is a promising physical treatment method for microalgae to improve total lipid production.
