Abstract
Exploration of alternative and sustainable sources of fuel production has become vital for a couple of decades because of the
increase in demand, shortages in inexpensive fossil fuel production, and environmental pollution caused by their derivatives.
Although a variety of renewable energy alternatives are currently available, energy derived from natural microalgae associated
with bacteria seems promising because it flourishes in all natural environments, along with contributing to the carbon cycle. Lipid
extraction from different microalgae cells is a significant boundary for the biofuel business because of the multifaceted nature of
the procedure and cell structure of the microalgae. Although the current existing dry extraction methods for lipid extraction from
algae are in use, the drying of microalgae is consuming more energy than the extraction itself. There is still lack of technology to
optimize the extraction of biodiesel from microalgae in a cost-effective and quick way. Studies show that eliminating the drying
step and extracting lipids in one step can be optimal by adding mechanisms like supercritical method, ionic liquids, Eutectic
solvents, and transesterification. A major constraint in this process is effective lipid extraction technique. Fuel production from
wet microalgae biomass is significantly desirable because it would eliminate at least two lengthy processes (dewatering and
drying) that consume much energy. In this study, wet extraction techniques are comprehended. For implementing and optimizing
this application, further research and exploration are much needed.
