5-Deoxy-5-fluoro-L-sorbose originating from 2-deoxy-2-fluoro-D-glucitol by fermentation with Acetomonas oxydans.

Using fermentation with a selected strain of Acetomonas oxydans it was possible to convert 2-deoxy-2-fluro-D-glucitol to 5-deoxy-5-fluoro-L-sorbose, in agreement with Bertrand's and Hudson's rule. The last-named compound was isolated in a yield of 88%. Both compounds were little toxic against Acetomonas oxydans.
