Abstract

Yeast single cell oil (SCO) is a non-crop-based, renewable oil source that can be used for the production of bio-based oleochemicals. Stand-alone production of SCO for oleochemicals is currently not cost-competitive because lower-cost alternatives from petroleum and crop-based resources are available. Utilizing low-valued nutrient sources, implementing cost-efficient downstream processes and adopting biotechnological advancements such as systems biology and metabolic engineering could prove valuable in making an SCO platform a reality in the emerging bio-based economy. This review aims to consider key biochemical pathways for storage lipid synthesis, possible pathways for SCO yield improvement, previously used bioprocessing techniques for SCO production, challenges in SCO commercialization and advantages of adopting a renewable SCO platform.
