Production of uncommon carotenoids and lipids by red yeasts utilizing agri-food residues and waste cooking oil.

ABSTRACT: In recent years, the biotechnological production of carotenoids and lipids by yeasts emerges as a valuable strategy at the industrial level, also fitting the circular economy pillars when agri-food waste can be used as the main components of the culture media. In this study, bioprocesses employing red yeasts were developed using cost-effective agri-industrial residues, such as soy okara (a soybean industry byproduct). This low-cost substrate was investigated as a source of carbohydrates and essential nutrients, with its enzymatic pre-treatment optimized to create a balanced and efficient fermentation medium. The screening of a collection of red oleaginous yeasts identified Rhodotorula paludigena CBS 6565 and Rhodotorula diobovata CBS 324 as promising strains capable of efficiently producin
