Abstract
Ethanol, ethylacetate and ethene were tested as no-substrates to improve prolonged 1,2-epoxypropane formation from propene by immobilized cells of three strains (Eu1, 2W, E3) of ethene-utilizing Mycobacteria. Cells grown either on ethene or on both ethene and ethanol were immobilised on lava and the effect of co-substrates on 1,2-epoxypropane formation from propene was recorded in a gas/solid bioreactor. The rate of 1,2-epoxypropane formation by immobilized cells of strains Eu1 and 2W was significantly enhanced when ethanol or ethylacetate were supplied simultaneously with propene, while biocatalysis during a prolonged period of time was achieved in the presence of ethylacetate. Co-substrates had no beneficial effect on 1,2-epoxypropane formation by strain E3. It was possible to increase the 1,2-epoxypropane formation rate by immobilized cells over a period of three weeks of operation by supplying propene and ethene alternately.
