“…Though temperature increase is not the mechanism of cell disruption, the increase in bulk temperature during treatment leads to a reduced nutritional value and protein digestibility (Janczyk et al, 2005), the decomposition of fragile compounds (Sheng et al, 2011) and an increased extraction of lipids (Sheng et al, 2012;Eing et al, 2013;Zbinden et al, 2013) and proteins (Coustets et al, 2013). The specific energy demand, calculated with literature data, strongly depends on the concentration of the suspension and ranges from 0.42 kWh/kg for 10% DCW (Eing et al, 2013) A C C E P T E D M A N U S C R I P T…”

“…Eing et al (2013) freeze-dried PEF-treated biomass and extracted with ethanol to obtain 70% of oil yield, which was about 4 times higher than untreated biomass [127]. However, freeze-drying is also a cell disruption, after which cells are usually observed with porous and loose cell wall structures for improved lipid extraction.…”

“…Eing et al (2013) found that oil could not be released to the medium after PEF due to the large volume of oil droplets [127]. Thus, PEF can facilitate the release of ionic compounds to realize a sequential selective recovery of hydrophilic compounds [149,150].…”

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.

“…A recent study [11] showed that the aqueous extraction of proteins from several microalgae followed the order: high-pressure cell disruption > chemical treatment > ultrasonication > manual grinding. The cell-wall of microalgae mostly fragile followed the order: Haematococcus pluvialis < Nannochloropsis oculata < Chlorella vulgaris, ≤ Arthrospira platensis [43].…”

ABSTRACT. Considering the high biodiversity of microalgae and their important impact on economy and ecological balance, new screening techniques are needed for their phenotypic characterization and efficient valorization of bioactive components. This represents one the key purpose of the emerging bioeconomy concept, involving new biorefinery technologies coupled with advanced analytical tools. The article presents an overview of the recent extraction and chemical techniques used to recover, separate and characterize the main bioactive molecules (lipids and fatty acids, carbohydrates, proteins and mycosporine-like amino acids chlorophylls and carotenoid pigments) syntesized by microalgae, considering their interesting applications in food, pharmaceutical and cosmetic industries. Special focuses will be directed towards the cell disintegration and extraction procedures, identification and quantification of main metabolites by advanced analytical techniques.
