Algae Fermentation by Mixed Culture of Lactic Acid Bacteria on Microfluidic Microbial Fuel Cell Platform for Continuous L-Lactic Acid and Bioelectricity Production

Abstract

Environmental concerns like plastic pollution and energy crises drive sustainable biopolymer and bioelectricity development. Biomass conversion, especially from macroalgae, addresses climate change. This study optimized L-LA production from Eucheuma denticulatum phycocolloid (EDP) via biotechnological routes and a microfluidic microbial fuel cell platform. High yields of D-galactose and L-LA were achieved using innovative ozonolysis and fermentation methods. A techno-economic analysis showed efficient production with integrated processes, making EDP a viable biomass for L-LA and bioelectricity co-production.
