Abstract

The properly dried and defatted mycelium of Rhizopus arrhizus constitutes a naturally immobilized lipase. The
mycelium was used to synthesize flavouring esters from fusel oil by esterification in organic solvents. Different
parameters like reaction medium, temperature, substrate concentration .and moisture level were optimized for the
synthesis of butyrate esters offusel oil. The mycelium was repeatedly used in batch reactions and was found to have high
efficiency and good operational stability. The halflife of the mycelial lipase was greatly int1uenced by the concentration
of substrates, i.e. the residual activity remained about the same after 20 cycles with low concentrations of substrates
(0.1 Meach). However, when concentrations of butyric acid and fusel oil were high, the rhyceliumrapidly lost its activity.
