Preparation of (R)-2-(4-Hydroxyphenoxy) propionic acid by biotransformation

Dingler, Christoph,Ladner, Wolfgang,Georg,Krei, Bryan Cooper,Hauerj, Bernhard

, p. 33 - 35 (1996)

With Beauveria bassiana Lu 700 as biocatalyst an ecologically beneficial process has been developed for the production of (R)-2-(4-hydroxyphenoxy) propionic acid. The fungal strain used in this process, B. bassiana Lu 700, is also a very suitable catalyst for the selective monohydroxylation of other aromatic carboxylic acids.
