Microbial Alchemy: Waste valorization for yeast oil production for a circular future

Abstract

The growing demand for sustainable solutions has driven researchersto exploremicrobial solutions for oil production using waste feedstock, enabling its valorization via oleaginous yeast strains. Depending on species and cultivation conditions these microbesaccumulate over 50% lipidsof their total cellularbiomass, by using various carbon sources from organic waste. This microbial-driven process not only reduces environmental burdens associated with waste disposal but also presents an eco-friendly alternative to conventional palm oil. By harnessing these microbes, industries can integrate circular economy principles, converting agricultural, industrial, and food waste into renewable lipid sources for biofuels, cosmetics, nutraceutical and food applications. This study explores various waste utilization approaches, the applications and challenges of yeast-derived oils, and future prospects, contributing to a more resource-efficient and sustainable future.
