Methylobacterium extorquwns microorganism useful for the preparation of poly-amp;bgr;-hydroxybutyric acid polymers

摘要

The present invention relates to a type of polymer comprising repeating units of formula ##STR1## and in particular to a poly-&bgr;- hydroxybutyrate polyester type polymer. The present invention also relates to a microbiological process for the production of the above type of polymer, to a methylotrophic microorganism (bacterium) for use in such a process, and to means for controlling such bioprocesses.
