Studies from Sardar Patel University Have Provided New Data on Carboxylic Ester Hydrolases (Enhanced Conjugation of Candida rugosa Lipase onto Multiwalled Carbon Nanotubes Using Reverse Micelles as Attachment Medium and Application in ...)

By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on Enzymes and Coenzymes is now available. According to news reporting originating in Gujarat, India, by NewsRx journalists, research stated, "Three liquid phases (viz. aqueous, nonaqueous, and reverse micelles) were scrutinized as medium for attachment of the enzyme Candida rugosa lipase (CRL) onto multiwalled carbon nanotubes (CNTs). The nanotubes were functionalized to attain carboxyl and amino groups on their surfaces before enzyme conjugation."

The news reporters obtained a quote from the research from Sardar Patel University, "Transmission electron microscopy and Fourier transformation infrared spectroscopic studies were used for characterization of the nanotubes during the course of functionalization. High enzyme loadings associated with the functionalized CNTs were observed when reverse micelles were used as the attachment medium. In addition, high activity in terms of ester synthesis in organic solvents was also observed while using those preparations. The nanobioconjugates prepared using reverse micelles were found to be highly sturdy and exhibited appreciable operational stability of around 95 +/- 3% at 20th cycle (in case of carboxylated nanotubes) and 90 +/- 5% at 10th cycle (in case of aminated nanotubes) for esterification."

According to the news reporters, the research concluded: "This shows the potential application of reverse micelles as the attachment medium for surface active enzymes such as CRL onto CNTs."
