Abstract
The biological production of lipids presents a sustainable method for generating fuels and chemicals. Recognized as safe and enhanced by advanced synthetic biology and metabolic engineering tools, yeasts are becoming versatile hosts for industrial applications. However, lipids accumulate predominantly as triacylglycerides in yeasts, which are suboptimal for industrial uses. Thus, there have been efforts to directly produce free fatty acids and their derivatives in yeast, such as fatty alcohols, fatty aldehydes, and fatty acid ethyl esters. This review offers a comprehensive overview of yeast metabolic engineering strategies to produce free fatty acids and their derivatives. This study also explores current challenges and future perspectives for sustainable industrial lipid production, particularly focusing on engineering strategies that enable yeast to utilize alternative carbon sources such as CO2, methanol, and acetate, moving beyond traditional sugars. This review will guide further advancements in employing yeasts for environmentally friendly and economically viable lipid production technologies.
期刊介绍：
Biological engineering is an emerging discipline that encompasses engineering theory and practice connected to and derived from the science of biology, just as mechanical engineering and electrical engineering are rooted in physics and chemical engineering in chemistry. Topical areas include, but are not limited to:
Synthetic biology and cellular design
Biomolecular, cellular and tissue engineering
Bioproduction and metabolic engineering
Biosensors
Ecological and environmental engineering
Biological engineering education and the biodesign process
As the official journal of the Institute of Biological Engineering, Journal of Biological Engineering provides a home for the continuum from biological information science, molecules and cells, product formation, wastes and remediation, and educational advances in curriculum content and pedagogy at the undergraduate and graduate-levels.
Manuscripts should explore commonalities with other fields of application by providing some discussion of the broader context of the work and how it connects to other areas within the field.
