“…Park et al (2008) and Kojima et al (2004) found that conventional diesel could be used instead of n-hexane as a solvent for C. rugosa lipase. tert-Butanol has been shown to stabilize the activity of Novozym 435 (Chen and Wu, 2003;Li et al, 2006;Royon et al, 2007). This forms the basis for the pilot plant production being tested in China (Du et al, 2008).…”

Enzymatic biodiesel production has been investigated intensively, but is presently employed industrially only in a 20,000 tons/year pilot plant in China (Du et al. [2008] Appl Microbiol Technol 79(3):331-337). This review presents a critical analysis of the current status of research in this area and accentuates the main obstacles to the widespread use of enzymes for commercial biodiesel transesterification. Improved results for enzymatic catalysis are seen with respect to increased yield, reaction time and stability, but the performance and price of the enzymes need further advances for them to become attractive industrially for biodiesel production. Critical aspects such as mass transfer limitations, use of solvents and water activity are discussed together with process considerations and evaluation of possible reactor configurations, if industrial production with enzymes is to be carried out. Results of published studies on the productivity of enzymes are also presented and compared to the use of chemical catalysts.

“…This suggests that not only soybean oil but also other oil sources can be directly used to synthesize biodiesel when methyl acetate is used as acyl acceptor. There were some researchers who utilized cotton-seed oil and rapeseed oil as the lipid feedstock for biodiesel production with methanol as methyl acceptor (Royon et al, 2007;Li et al, 2006). The ME yields in that case were 95% and 95%, respectively.…”

Biodiesel is an alternative diesel fuel made from renewable biological resources. During the process of biodiesel production, lipase-catalyzed transesterification is a crucial step. However, current techniques using methanol as acyl acceptor have lower enzymatic activity; this limits the application of such techniques in large-scale biodiesel production. Furthermore, the lipid feedstock of currently available techniques is limited. In this paper, the technique of lipase-catalyzed transesterification of five different oils for biodiesel production with methyl acetate as acyl acceptor was investigated, and the transesterification reaction conditions were optimized. The operation stability of lipase under the obtained optimal conditions was further examined. The results showed that under optimal transesterification conditions, both plant oils and animal fats led to high yields of methyl ester: cotton-seed oil, 98%; rapeseed oil, 95%; soybean oil, 91%; tea-seed oil, 92%; and lard, 95%. Crude and refined cottonseed oil or lard made no significant difference in yields of methyl ester. No loss of enzymatic activity was detected for lipase after being repeatedly used for 40 cycles (ca. 800 h), which indicates that the operational stability of lipase was fairly good under these conditions. Our results suggest that cotton-seed oil, rape-seed oil and lard might substitute soybean oil as suitable lipid feedstock for biodiesel production. Our results also show that our technique is fit for various lipid feedstocks both from plants and animals, and presents a very promising way for the large-scale biodiesel production.

“…For example, Li et al, reported that the combined use of Lipozyme TL IM and Novozym 435 at a ratio of 3:1 gave the highest degree of methanolysis and subsequently produced a biodiesel yield of ca. 95 in a batch system 17 . Lee et al determined that the mixed enzyme of R. oryzae lipase and C. rugosa lipase gave a higher yield of biodiesel than a single lipase 19 .…”
