Abstract
The use of Rhizopus delemar lipase to specifically and mildly isolate industrially interesting fatty acids from new agricultural oil seed crops was evaluated. R. delemar-mediated hydrolysis of Crambe and Dimorphotheca oils was studied in an emulsion system at room temperature. Crambe oil hydrolysis was also studied using lipase, immobilized in a two-phase hollow-fiber membrane bioreactor. Progress of the hydrolysis was monitored by GLC analysis. Allowing the reaction to proceed in an oil - water emulsion gave a high yield of erucic acid when using Crambe oil, and dimorphecolic acid when using Dimorphothecaoil. R. delemar-mediated hydrolysis of Crambe oil in a membrane bioreactor also yielded high proportions of erucic acid, albeit at a lower apparentrate. It is concluded that lipases with 1,3-positional specificity can be used to produce high concentrations of specialty fatty acids from novel vegetable oils and that immobilization of these lipases in membrane bioreactors allows re-use of the enzyme, thus potentially increasing cost-effectiveness of the reaction.
