Acetomonas oxydans

The first cyclic intermediate on the shikimate pathway is 3-dehydro-quinic acid (38) and it was first obtained by Weiss, Davis and Mingioli from cultures of Escherichia coli mutant 170-27 by charcoal chromatography and precipitation of the brucine salt. Probably the first chemical preparation of this biochemical intermediate was reported by Hesse in 1859 who oxidised (—)-quinic acid (42) with bromine water Several procedures have since been reported for the preparation of this metabolite Yields of almost 80 per cent of 3-hydroquinic acid (38) were reported by Whiting and Coggins after a seven-day incubation of (—)-quinic acid (42) with Acetomonas oxydans CR-49 and similar selective oxidation of the axial 3-hydroxyl group in (—)-quinic acid with nitric acid or platinum and oxygen " forms the basis of chemical methods of preparation. 

Gluconobacter (Acetomonas) G. oxydans. Produce acetic acid in beer sometimes giving a cidery note.
