Lipase-catalyzed transesterification of oil feedstocks has been
considered as one of the most promising techniques for producing
biodiesel, a mixture of fatty acid alkyl esters (FAAE). This process
has become a research hot-spot in academic community during
last 10 years. An increasing number of scientific publications
including articles, review papers, book chapters, patents and
conference abstracts have been published (Fig. 1). However, conventional biodiesel plants adopt transesterification processes
using chemical catalysts such as alkalis and acids. Only a few
plants have employed enzymatic process for industrial productions of biodiesel
