The formation of lactose caprate from lactose sugar and capric acid, using free lipase (free-CRL) and lipase immobilized on nanoporous mica (NER-CRL) as a biocatalyst, was evaluated through a kinetic study. The apparent kinetic parameters, K-m and V-max, were determined by means of the Michaelis-Menten kinetic model. The Ping-Pong Bi-Bi mechanism with single substrate inhibition was adopted as it best explains the experimental findings. The kinetic results show lower K-m values with NER-CRL than with free-CRL, indicating the higher affinity of NER-CRL towards both substrates at the maximum reaction velocity V-max,V-app > V-max). The kinetic parameters deduced from this model were used to simulate reaction rate data which were in close agreement with the experimental values.en-USlipase immobilizationmicakinetic studyPing-Pong Bi-Bi modelsugar ester synthesisArticle14461450758
