Working Group 2

Task (b) Cell disruption

In contrast to conventional agricultural crops, microalgae biomass is single cell biomass. The individual microalgal cells are surrounded by surprisingly though cell wall. This makes extraction of bioproducts from the biomass difficult. Therefore, cell disruption is required to enhance the yield of extraction of bioproducts from the biomass. Important criteria for developing new cell disruption technologies are the impact on the quality of the bioproducts, the enhanced extraction efficiency of bioproducts and the cost and energy demands. Methods that will be explored include physical disruption methods (pulsed electric field, bead-beating, high pressure homogenization) and cell lysis techniques (enzymatic hydrolysis, high temperature treatment).
