Technical feasibility of residual biomass of microalgae Desmodesmus sp. after supercritical extraction: evaluation of chemical composition

Supercritical extraction process has been used to obtain bioactive compounds from microalgae biomass that differs in composition because it has protein, esters, carotenoids, chlorophyll, enzymes, antibiotics, vitamins, and hydrocarbons. Due to this, the study of the technical feasibility of supercri...
