Low-cost Fermentation of Polyhydroxyfatty Acid Esters

With the depletion of traditional fossil energy and environmental problems, there is an urgent need for alternative materials. Biosynthesis not only achieves low-carbon green economy, but also reduces energy consumption. Polyhydroxyfatty acid ester is a kind of material with excellent performance, but the production cost is high, mainly due to the high cost of fermentation carbon source, fermentation process and other factors. Using waste as substrate not only reduces fermentation costs but also solves environmental problems. On the other hand, mixed strains can be used simultaneously to reduce the cost of fermentation.
