This thesis project is a contribution to addressing the pressing need for sustainable alternatives to fossil fuels and traditional plastics. The work focuses on enzymatic saccharification of microalgae biomass to generate a sugar-rich stream as raw material for biofuels and bioplastics production. Microalgae and cyanobacteria are highlighted for their ability to convert CO2 into valuable biomass components in the presence of light. To enhance biomass conversion efficiency, the enzymatic hydrolysis of microalgae and cyanobacteria is explored by utilizing various enzymes to break down complex polymers into valuable sugars. Additionally, the cultivation of cyanobacteria is studied to optimize the overall process. Results indicate challenges, such as measurement uncertainty and the need for biomass pretreatment, suggesting areas for further research. The primary objective of this thesis work is to optimize enzymatic hydrolysis processes by determining the optimal combinations of enzymes, to enhance biomass conversion efficiency. It also underscores the importance of microorganisms in transitioning to a more environmentally friendly future by offering sustainable alternatives to conventional products.
