Microalgae as a multipotential role in commercial applications: Current scenario and future perspectives

Microalgal feedstocks have gained tremendous potential for sustainable biofuel production in recent years. For biofuel processing, thermochemical, biochemical, and transesterification processes are used. Many researchers have recently become interested in the hydrothermal liquefaction of microalgae. Renewable biofuel production from microalgae, as well as a broad range of value-added co-products, describe its potential as a biorefinery feedstock from this perspective. Microalgae convert solar energy into carbon storage compounds, such as TAG (triacylglycerols), which can then be converted into biodiesel, bioethanol, and bio-methanol. Microalgae are considered to be the most attractive source of biofuel production for all the organisms used. This review explored the percentage of oil content, chemical composition, and lipid content of microalgae. This analysis depicts the various aspects of microalgal species for biofuel conversion. Also, other bioenergy and value-added items are discussed briefly.
