| Abstract: | The esterification catalyzed by immobilized lipase on silk in organic solvents are studied. The influence of the nature of organic solvents, carbon chain length , substrates, temperature, pH value and water content in the system on the activity of immobilized lipase on silk are investigated. The experimental results show that the highest activity of immobilized lipase can be attained at 50 and pH value 7.4 in isooctane. The operational half|life time of immobilized lipase on silk catalytic esterification is about 120 h. |
