[Progress on microbial glyceride biosynthesis and metabolic regulation in oleaginous microorganisms].

Oleaginous microorganisms are small portion of organisms that have ability to accumulate lipids over 20% of their biomass. These species can transform renewable material into microbial oil with similar fatty acid composition to that of plant-based oil. Some organisms may also produce glycerides with high content of poly-unsaturated fatty acids. Therefore, microbial lipids are considered as potential oil resource. Summarized here are some features of oleaginous species and recent developments on their biosynthetic machinery and metabolic regulation mechanism.
