“…For instance, to produce xylitol from lignocellulosic biomass using biological route, the yeast S. cerevisiae PE-2-GRE3 (yeast engineered for xylitol production, with overexpression of GRE3 gene from Pichia stipitis) and an enzyme cocktail of cellulases and hemicellulases were used in simultaneous saccharification and fermentation process and showed interesting conversion results (Baptista et al, 2020). In addition to engineered organisms, native yeasts have been identified and evaluated for their ability to accumulate xylitol, especially yeasts of the genera Spathaspora and Scheffersomyces, which have been essential to promote advances in the fermentation and production processes in single or co-culture, besides enabling the identification of genes of interest for metabolic engineering (Hickert et al, 2013;Farias and Maugeri-Filho, 2021;Neitzel et al, 2022;Scapini et al, 2022).…”

It is mandatory to make the circular economy a reality, developing ways of transforming waste into valuable products. In this context, investigating the biotechnological potential of different residues is most welcome. This review analyzes how orange waste can be used as biorefinery feedstock to produce different bioproducts using yeasts as the major biocatalysts. In addition to the current orange market, its pectin-rich biomass is described in detail, aiming to elucidate how yeast cells can convert it into ethanol, xylitol, polyphenols, and organic acids (some of them, volatile compounds). Genetic, metabolic, and evolutionary engineering are also analyzed as biotechnological tools to improve the existing processes. Finally, this review also addresses the potential employment of fruit-dwelling yeasts in biorefining pectin-rich biomasses such as orange wastes. All the data presented herein lead to the conclusion that these residues could already be used for noble purposes.
