Recovering lipids and proteins from microalgal biomass requires the microscopic cells to be ruptured. The Algal Processing Group has shown that by processing pre-concentrated biomass, this can be done in an energy efficient manner at large scale using high pressure homogenisation. We have also shown that efficient processing of microalgal biomass is highly dependent on the species of microalgae and that the growth conditions alter physical attributes of the microalgal cells relevant to cell rupture, such as cell size and cell wall thickness and strength. We are currently investigating the recovery of proteins from microalgae in relation to food and feed applications.
