• How do you extract oil from algae?
  • Oil press or Mechanical press The oil can be extracted from algae using a mechanical press, as seen in figure 1. This process¡ªwhich forces the algal paste into a nozzle that removes oil and expels much drier biomass¡ªcan extract up to 70% of the algal oil, but generally requires a dry algae feedstock. Dry algae is the product of dewatering.
  • Can microalgae be used for biofuel production?
  • Biofuel production from microalgae is a promising option to contribute for the resolution of the eminent crisis of fossil energy and environmental pollution specially in the transporting sector. The choice of lipid extraction method is of relevance and associated to the algae morphology (i.e., rigid cells).
  • Are microalgae a candidate for bio-oil production?
  • Due to their high lipid content and rapid development rates, microalgae, a varied collection of microscopic photosynthetic organisms, have emerged as a candidate for bio-oil production (Wang et al., 2022). Compared to conventional oil crops like soybeans and corn, microalgae provide a number of benefits.
  • Why is oil extraction from wet microalgae important?
  • In this direction, it is convenient to remark that the study of oil extraction from wet microalgae is fundamental because the presence of water acts as a barrier between the solvent and the intracellular oil, but the dry step also implies additional costs and energy consumption ( Park et al., 2020 ).
  • What is microalgae-based bio-oil production?
  • Microalgae-based bio-oil production is a viable and sustainable method to produce renewable energy and sustainable biofuels (Raheem et al., 2018).
  • Can microalgae be used as bio-oil feedstocks?
  • Various popular microalgae have been the focus of intense research due to their potential applications. Both Chlorella vulgaris and Nannochloropsis sp. have shown potential as bio-oil feedstocks; these algae are high in lipid content and can grow quickly in a variety of water conditions.
