Future bioenergy source by microalgae–bacteria consortia: a circular economy approach

Abstract

Future sustainable approach of bioenergy production that uses microalgae–bacteria consortium to produce bioelectricity and biofuel for industrial and daily activities.

Microalgae-bacteria nexus for environmental remediation and renewable energy resources: Advances, mechanisms and biotechnological applications

“…Microalgae constitute a considerable amount of their dry weight as lipids and carbohydrates. These have garnered the opportunity to apply algal biomass as feedstock for the production of biofuels including biodiesel, bioethanol, biohydrogen and biogas [ 1 , 56 ]. The utilization of microalgae as a biofuel source has been explored since the 1950s.…”

“…In terms of techno-economic evaluation, the current approach of converting microalgae biomass into biofuel is economically not feasible requiring more research in the future to make it suitable for commercialization [ 256 ]. Microalgae cultivation in the microalgae-bacteria consortium could significantly reduce this problem, and enhance the yield of biomass and biohydrogen [ 56 ]. While using microalgae as a bioethanol source offers carbo-neutral fuel alternatives, the requirement of pre-treatment of its biomass before the fermentation process has been one of the application challenges [ 75 ].…”
