Abstract
Oleaginous yeast represents a promising biotechnological platform for the sustainable production of bio-oil, an alternative to fossil-derived fuels. These microorganisms can accumulate lipids up to 20–70% of their dry cell weight, primarily in the form of triacylglycerols that are structurally similar to plant and animal oils. Among them, certain species exhibit distinctive red or pink pigmentation and are collectively referred to as red yeasts. These yeasts not only synthesize significant amounts of storage lipids but also produce valuable carotenoid pigments such as β-carotene, torulene, and torularhodin. The dual ability to generate bio-oil and natural pigments provides a unique advantage for developing integrated bioprocesses. Furthermore, red yeasts can efficiently utilize low-cost and renewable substrates, including agro-industrial residues and food waste, thereby reducing production costs and supporting waste valorization. Advances in metabolic engineering, fermentation optimization, and waste valorization are further expanding their potential for large-scale lipid synthesis. Consequently, red yeast provides a robust and sustainable platform for bio-oil and bio pigment production, aligning with global efforts toward renewable energy and reduced carbon emissions.
Keywords: Red yeast, lipid accumulation, natural pigment, sustainability.
