Plastics from Bacteria

For industrial applications, the controlled incorporation of repeating units with different chain lengths into other copolymers is desirable. Thus, polyesters can be produced with tailored properties. [Pg.179]

Such copol5mers can be produced under controlled growth conditions as a defined mixture of substrates for a certain type of microorganisms is offered. In this way, a well defined and reproducible copolymer will be formed (22). PHAs can be produced by both wild-t e and recombinant bacteria. The production of medium chain length PHAs occurs in pseudomonas (23). [Pg.179]

Since a wide variety of bacteria are accumulating PHAs as intracellular storage material this natural polymer is considered as a potential substitute for petrochemical plastics (24). Medium chain length t es are semicrystalline elastomers with a low melting point. [Pg.179]

Tropical mangrove and marine ecosystems from India have been screened for promising bacteria, that have the capability of accumulating high amounts of PHA (25). From 866 bacterial cultures isolated from this region, 337 cultures were scored positive for the PHA production. Amongst these isolates, seven cultures accumulated more than 1 gl in the culture broth. The thin layer chromatograms of the methyl esters of PHA from the seven cultures showed varied profiles. The sediment samples also showed the presence of PHA with five different monomeric units. [Pg.180]

Other microbial plastics are polymers from lactic acid, succinic acid, poly(ethylene) ethylene from ethanol and its polymer poly-(ethylene), 1,3-propanediol, as weU as poly(p-phenylene) (23). [Pg.180]
