Enzyme immobilization for biodiesel production.

Biodiesel has attracted more and more attention in recent years because of its biodegradability, environmentally friendliness, and renewability. Contrary to the conventional chemical catalysis method to produce biodiesel, the biochemical catalysis method developed quickly in the past decade and many immobilized enzymes are commercially available to meet the large-scale industrialization of biodiesel. This review is focusing on the current status of biodiesel production by biochemical catalysis method, especially the commercial enzyme and its immobilization for biodiesel production. Consequently, we believe that biochemical catalysis with immobilized enzymes is bound to be an alternative method instead of chemical catalysis in biodiesel production in the near future.
