3.2. Fungal pelletization assisted bio-flocculation of microalgae
Due to relatively small cell size (1–70 lm) and low algal cell
density (typically between 0.5 and 5.0 g/L) of algal biomass, harvesting
microalgae from culture broth is energy intensive and
costly. Therefore, development of alternative harvesting technologies
for efficient harvesting system is urgently needed. In this
study, fungi-assisted bio-flocculation strategy for efficient and
low-cost harvesting relatively diluted algal cells in culture broth
was developed and evaluated.
