Progress in Lipases, Its Immobilization and Application in Biodiesel Preparation with Emphasis on Our Practice

Abstract

Biodiesel is one of the most ideal renewable energies. Among its preparation technologies, biological technology exhibits the most promising prospect. However, high operation cost of lipase and easy inactivation are the main obstacles for large scale industrialization of enzymatic catalyzed biodiesel production. To solve these bottlenecks, such strategies have been employed as producing the cheapest and most tolerable lipases, developing better catalysis techniques, and further bio-refining byproduct glycerin of biodiesel into high-valued products. Eventually, enzymatic catalyzed technology has been succeeded in industrializing with good commercial efficiency. This article reviews a decade endeavor on research and practice of these strategies.
