A Review of The Micro-Algae Are Being Harvested to Make Biofuel

Effective harvesting is seen by many researchers as the main obstacle to the commercialization of microalgal biofuel. The small size of micro-algal cells, the cells' similar density to the growth medium, the algae's negative surface charge, and the algae's faster growth rates than terrestrial plants present additional difficulties for harvesting micro-algae. Sedimentation, flocculation, floatation, centrifugation, filtering, or any combination of these procedures can be used to collect algae. The numerous techniques for gathering and dehydrating microalgae for the creation of biofuel are reviewed in this research.
