Microalgae harvesting is critical to remove water from algal growth media with solidliquid separation. Bioflocculation has the same principle as flocculation. Using solidliquid separation, microalgae harvesting removes moisture from the algal growth
substrate. The same idea underlies flocculation and bioflocculation. Using fungal and
bacterial bioflocculants requires a special medium that is different from the microalgae
medium, that fungi and bacteria can contaminate microalgae, so it is not recommended
to be used as a bioflocculant agent. Microalgae Anabaena sp. was chosen in this study
as a bioflocculant agent since it can produce exopolysaccharides (EPSs). Dissolved
proteins and carbohydrates make up EPSs. This investigation looked into employing
Anabaena species to extract Chlorella species. The harvest day was used to measure the
parameters. A spectrophotometer was used to measure the precipitation percentages.
Bligh and Dyer's methods were used to measure lipid contents. The phenol-sulfate was
used to perform carbohydrates. Bradford method was used to quantify proteins. The
ratio of 1:1.25 was determined to have the best proportion of flocculation and
carbohydrate content (Chlorella sp. : Anabaena sp.). The ratio of 1:1 was determined to
have the maximum cell lipid and protein content (Chlorella sp.: Anabaena sp.). The
application of this study will be beneficial to design effective methods for harvesting
microalgae using biological materials such as other microalgae.
