Dear everybody,
        I want to assay oxidase activity of an oxygenase enzyme from
bacteria. This enzyme oxidizes benzene to phenol and toluene to a mixture of
cresols (o-, m- ,p-). The assay method we used now is based on GC assay but
this is laborious. I would like to know whether there are any sensitive
colourimetric or fluorometric assay for detection of phenol and cresol.
        Thank you for your attention.

Yours sincerely,
