Microalgae are becoming an important source of high-value products such as
biostimulants, biopesticides, and other low-value products like biofertilizers or aquafeed
(fatty acids and carotenoids) among others. However, extracting the biomolecules
contained in the microalgae cells is difficult due to the structure and composition of the
microalgal cell wall. To overcome this drawback, mechanical cell disruption methods
such as high-pressure homogenization (HPH), can be applied to facilitate extracting the
compounds of interest.
This work focuses on optimizing the extraction of two major groups of products
from microalgae biomass - biostimulants and biofertilizers. The aim of this research is to
study the effect of the HPH pre-treatment on the production of these different bioproducts
starting with Scenedesmus sp. biomass grown in pig sludge as the raw material.
For each product the pre-treatment of the wet biomass by HPH must to be
optimized to select the optimal conditions ...
