Abstract

We proposed a simple; energy-efficient and environmental friendly method to extract green crude oil from microalgae by using dimethyl ether (DME). In this study; this method was tested on several species of natural blue-green microalgae. Consequently; the green crude was successfully directly extracted from highmoisture microalgae (78.2–93.4 % water content) with an extraction rate ranging from 9.9 to 40.1 % of the dry weight of the microalgae. The extraction yield of total green crude on these species by liquefied DME was compared to the widely-used Bligh-Dyer’s method. The DME method almost achieved an extraction capacity approximately equivalent to the Bligh-Dyer’s method. Furthermore; the dewatering properties of the proposed method on several species of wet microalgae; and the extraction efficiency were also investigated.
