The present invention relates to a process for the production of poly
(hydroxy fatty acids) as well as recombinant bacterial strains for
carrying out the process. In addition, new poly(hydroxy fatty acids) and
new substrates for the production of conventional and new poly(hydroxy
fatty acids) are described. Moreover, the invention also relates to a DNA
fragment, which codes for a PhaE and a PhaC component of the poly(hydroxy
fatty acid) synthase from Thiocapsa pfennigii, as well as the
corresponding poly (hydroxy fatty acid) synthase protein.
