Abstract
This invention relates to a process for producing polyester biopolymers by culturing Pseudomonas oleovorans bacteria on substrates comprising certain nutrients. The nature of the polyesters can be varied by varying the nature of the carbon source used. In this way polyesters with unsaturated double bonds can be produced, too. From the polyesters, optically active carboxylic acids or esters are produced. The polymers can be used for making articles of manufacture, such as sutures, films, skin and bone grafts.
