Abstract
The low productivity of microalgae has restricted scale-up application of microalgae-based biodiesel processes. Diethyl aminoethyl hexanoate (DA-6) was investigated to enhance the biomass and metabolite productivity. At a very low concentration (10â7 M) DA-6 made Chlorella ellipsoidea SDEC-11 and Scenedesmus quadricauda SDEC-13 obtain enlarged cell size, 114 mg Lâ1 dâ1, 101 mg Lâ1 dâ1 biomass productivity and 39.13 mg Lâ1 dâ1, 32.69 mg Lâ1 dâ1 lipid productivity, respectively. Biomass and lipid productivity of SDEC-11 and SDEC-13 were 100 mg Lâ1 dâ1 and 30.05 mg Lâ1 dâ1, 94 mg Lâ1 dâ1 and 28.43 mg Lâ1 dâ1, respectively, without DA-6. Twice hormone dose in 10â6 M DA-6 medium resulted in higher biomass productivity (106 mg Lâ1 dâ1) and longer exponential growth of SDEC-13. DA-6 also ensured the property of microalgae biodiesel to meet the EN 14214 standard. The current investigation demonstrated that DA-6 accelerated the microalgae growth and simultaneously improved the quality and quantity of lipid for biodiesel production.
