Abstract
Disclosed is a process for the preparation of aliphatic carboxylic acids by microbial oxidation of alcohols with relatively long, optionally branched C chains by means of atmospheric oxygen, in which the bacteria species Gluconobacter roseus is used as the microorganism. Contemplated is the use of Gluconobacter roseus strain IAM 1841 to oxidize n-butanol, isobutanol, 2-methylbutanol and 3-methylbutanol to the corresponding acids. Also contemplated is the use of Gluconobacter roseus strain IFO 3990 to oxidize isobutanol, 2-methylbutanol and 3-methylbutanol to the corresponding acids.
