“…The substitution of H2O2 with the persulfate ion (S2O8 2-) was also investigated. The persulfate ion reacted with Fe 3+ to generate SO4 •and S2O8 •radicals instead of the ‧OHradicals of the typical Fenton reaction (Seo et al, 2016). The persulfate reagent at 2mM concentration led to improved lipid extraction yield 95%, compared to 80% for 0.5% (v/v) H2O2 at the same pretreatment conditions.…”

“…High lipid extraction recoveries have been reported by this approach, but energy consumption is relatively high majorly due to the low biomass concentrations. Moreover, the cost of chemicals in this approach is much higher than inorganic acids and alkalis [181], impeding the industrial implementation of this method.…”

Lipid recovery from wet oleaginous microbial biomass for biofuel production: A critical review

et al. 2016

h i g h l i g h t sChallenges in industrial lipid extraction processes were illustrated. Lipid recovery from wet biomass was critically reviewed in the context of biofuel productions. Cell wall disruption technologies were critically reviewed and compared. a b s t r a c tBiological lipids derived from oleaginous microorganisms are promising precursors for renewable biofuel productions. Direct lipid extraction from wet cell-biomass is favored because it eliminates the need for costly dehydration. However, the development of a practical and scalable process for extracting lipids from wet cell-biomass is far from ready to be commercialized, instead, requiring intensive research and development to understand the lipid accessibility, mechanisms in mass transfer and establish robust lipid extraction approaches that are practical for industrial applications. This paper aims to present a critical review on lipid recovery in the context of biofuel productions with special attention to cell disruption and lipid mass transfer to support extraction from wet biomass.

“…The recovered lipid from wet microalgae was subjected to treatment using persulfate-based oxidation with ferric chloride as a coagulant in order to eliminate the dewatering step. In this study, microalgal cells were first harvested by adding 200 mg L -1 of FeCl 3 (as a coagulant) and extraction was performed using persulfate based oxidation by addition of potassium persulfate, which eventually lead to the recovery of 95% of lipid (Seo et al, 2016).The persulfate based extraction does not require organic solvent for extraction process and can be directly applied to wet biomass.…”

With increasing global population and depleting resources, there is an apparent demand for radical unprecedented innovation to satisfy the basal needs of lives. Hence, non-conventional renewable energy resources like biodiesel have been worked out in past few decades. Biofuel (e.g. Biodiesel) serves to be the most sustainable answer to solve "food vs. fuel crisis". In biorefinery process, lipid extraction from oleaginous microbial lipids is an integral part as it facilitates the release of fatty acids. Direct lipid extraction from wet cell-biomass is favorable in comparison to dry-cell biomass because it eliminates the application of expensive dehydration. However, this process is not commercialized yet, instead, it requires intensive research and development in order to establish robust approaches for lipid extraction that can be practically applied on an industrial scale. This review aims for the critical presentation on cell disruption, lipid recovery and purification to support extraction from wet cell-biomass for an efficient transesterification.
