ABSTRACT:
Disclosed is a novel process for the production of pyrocomenic acid [3-hydroxy-4(1H)-pyran-4-one and rubiginol [3,5-dihydroxy-4(1H)-pyran-4-one, which are starting materials for synthesis of maltols useful as food spices as well as additives for cosmetics.
The chemical reactions possibly taking place in the fermentation and the heating post-treatment thereof in the present invention are shown as follows: ##STR1## The microorganisms usable in the above oxidation fermentation include Gluconobacter rubiginosus IFO 3244, Gluconobacter suboxydans IFO 3254, Gluconobacter melanogenus IFO 3293, Pseudomonas fluorescens IFO 3081, Erwinia carotovara IFO 3380 etc.
