Effect of diethyl aminoethyl hexanoate on the accumulation of high-value biocompounds produced by two novel isolated microalgae.
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 (10(-7)M) DA-6 made Chlorella ellipsoidea SDEC-11 and Scenedesmus quadricauda SDEC-13 obtain enlarged cell size, 114mgL(-1)d(-1), 101mgL(-1)d(-1) biomass productivity and 39.13mgL(-1)d(-1), 32.69mgL(-1)d(-1) lipid productivity, respectively. Biomass and lipid productivity of SDEC-11 and SDEC-13 were 100mgL(-1)d(-1) and 30.05mgL(-1)d(-1), 94mgL(-1)d(-1) and 28.43mgL(-1)d(-1), respectively, without DA-6. Twice hormone dose in 10(-6)M DA-6 medium resulted in higher biomass productivity (106mgL(-1)d(-1)) 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.
