A far-red fluorescent probe for sensing laccase in fungi and its application in developing an effective biocatalyst for the biosynthesis of antituberculous dicoumarin

Abstract

A far-red fluorescent probe has been developed for sensing fungal laccase. The probe was used to determine that Rhizopus oryzae had a high level endogenous laccase amongst 24 fungal strains. The Rhizopus oryzae was then used as a biocatalyst for the preparation of dicoumarin resulting in significant inhibition of Mycobacterium tuberculosis H37Ra.
