Enzymes in certain bacteria help to produce a host of natural, biodegradable polyesters from basic nutrients.

Bacterial bioplastics are polyesters produced naturally by certain bacteria. These polyesters serve as carbon stores when carbon is plentiful but limited supplies of other nutrients make continued growth and reproduction impossible. The variety of s that these bacteria produce is quite broad. In addition, the enzymes responsible for polyester polymerization are so flexible that they can theoretically the polymerization of any simple organic molecule that contains the appropriate hydroxyl (OH) and carboxyl (COOH) groups needed to form an “ester” bond.
