| Abstract: | Summary The biotransformation of 2-acetylthiophene by 800 strains of micromycetes has been investigated. Among them, 460 strains have been selected on solid media and cultivated in a liquid synthetic medium. Of these, 106 strains were able to completely deplete 2-acetylthiophene with or without production of intermediary metabolites. 2-Thienylglyoxylic acid was not detected but 72 strains produced 2-thiophenecarboxylic acid. Among them, eight strains have been selected for further optimization of this bioconversion. |
