Subject:
Bacillus mycoides; Fourier transform infrared spectroscopy; acetone; algae; algal oils; biodiesel; carboxylic ester hydrolases; commercialization; glutaraldehyde; hexane; methanol; molecular weight; pH; temperature; transesterification
Abstract:
... Methanol induced lipase inactivation is the major hindrance in commercialization of enzyme catalyzed biodiesel production. Thus, methanol tolerance is highly needed for the lipase to be used in transesterification reaction. Hence, by virtue of such desirability, a methanol tolerant, extracellular lipase FDS8(L) was extracted from Bacillus mycoides strain CV18 and purified to homogeneity with 22.3 ...
