Microalgae Oil Extraction Pre-treatment Methods

Abdel Ghaly, Dahouse University, Canada reviewed on microalgae oil extraction Pre-treatment methods and comparatively analyzed.

Microalgae biomass can be used to produce numerous value added products such as biodiesel, bio-ethanol, biogas, bio-hydrogen, fish feed, animal feed, human food supplements and skin care products. Production of value added products from microalgae biomass requires the growth and recovery of the algae biomass, extraction and downstream processing of the desired product.

One of the major obstacles for using microalgae biomass on an industrial-scale, for the production of biodiesel, is the high processing costs. Increasing the lipid recovery efficiency from the microalgae biomass would result in greater product yields (biodiesel).

Thus, the aim of this study was to review the current methods used for microalgae pre-treatment and perform a comparative analysis in order to determine the most economically efficient method for large scale use. The effectiveness of the pre-treatment methods investigated was evaluated based on: (a) cell wall disruption efficiency, (b) cost, (c) toxicity (d) suitability for large scale use, (e) time, (f) reusability and (g) maintenance.
