A class of biopolymer including sulfur in the form of a thioester in the polymer backbone or a thioether in the polymer side chains has been developed. These are preferably produced by fermentation of bacteria with appropriate sulfur containing substrates, which are incorporated by a broad spectrum polyhydroxyalkanoate ("PHA") polymerase. The sulfur-containing PHAs allow various applications and uses in industry. Representative embodiments of the applications of the sulfur-containing PHAs include their uses in the packaging industry, medicine, pharmacy, agriculture or food industry, as active agents or as coatings, packaging, or carriers.

Una clase del biopolímero incluyendo el sulfuro en la forma de un thioester en la espina dorsal del polímero o de un thioether en las cadenas laterales del polímero se ha desarrollado. Éstos son producidos preferiblemente por la fermentación de bacterias con el sulfuro apropiado que contiene los substratos, que son incorporados por una amplia polimerasa del polyhydroxyalkanoate del espectro ("PHA"). El PHAs con sulfuro permite varios usos y aplicaciones en industria. Las encarnaciones representativas de los usos del PHAs con sulfuro incluyen sus aplicaciones en la industria de empaquetado, la medicina, la farmacia, la agricultura o el sector alimenticio, como agentes activos o como capas, el empaquetado, o portadores.
