Optimising Chlorella vulgaris bioflocculation by Aspergillus Niger pellets and their application in wastewater treatment and lipid production

Fungal preformed pellets may have a better chance of forming into an efficient bio-flocculation method to harvest microalgae than the fungal spore-assisted approach, which takes a long time, produces a small number of pellets or loose pellets that lack shape or structure, and sometimes growth appears as deposits, also turning algal growth into a yellow color. The pellet-assisted technique shows excellent ability to remove phosphate and ammonium from wastewater. A suitable biovolume must be considered to achieve ideal treatment in wastewater remediation, and adding glucose can improve overall effectiveness.
