There have been substantial improvement and technological
advancement in the drying and disruption of microalgae. Optimizing
the stages of algae drying and disruption would not only help
to reduce the cost but can also render the production scheme economically
viable. It can be concluded based on the review that for
realistic applications that make economic sense, the issues of
energy and cost to mass production of algal intracellular products
and biofuels must be tackled. As energy efficient and cost-effective
harvesting are two major challenges in the commercialization of
biofuels from algae, research addressing these challenges ought
to be intensified.
