Abstract

Lignocellulosic byproducts, mainly generated by the agro-industrial sector, have great potential as cost-effective feedstocks for bioprocesses because of their abundant availability and high content of sugar-rich and nutrientrich elements. This biomass can be employed as a carbon source to produce various molecules using several microorganisms. Yeast strains have shown their capability to metabolize diverse C5 and C6 carbon sources, thereby facilitating their use in the bioprocessing of lignocellulosic biomass. Furthermore, yeasts can produce a wide range of valuable products, including biofuels, enzymes, proteins, and pigments, making them attractive for use in integrated biorefineries. Yeast-derived pigments have versatile applications and are environmentally friendly alternatives to their synthetic counterparts. This review emphasizes the potential of lignocellulosic biomass as a feedstock for producing yeast-derived products with a focus on pigments as valuable molecules. It also proposes a yeast-derived pigment platform utilizing lignocellulosic byproducts and explores its potential integration in biorefineries. (AU)
