Most microbially produced polymers are known to be stiff and not very flexible. However, one potential microbially derived polymer that is more supple is a lactic acid-P-methyl-5-valerolactone( M5VL)-lactic acid triblock copolymer. This was demonstrated by the overproduction of mevalonate in E. coli via enzymes from L. casei which generate mevalonate, a precursor of the isoprenoid pathway, from acetyl-CoA. Mevalonate is produced at over 80gl from glucose, dehydrated, and then reduced to form M WL. PLA-PPM5VL-PLA triblock copolymers were created to demonstrate physical properties such as elasticity and toughness [141]. [Pg.164]

A series of papers has been published on the direct degradation of a variety of polyesters in the ion source of a mass spectrometer. Polymers examined were poly(/3-propiolactone), poly(/S-pivalolactone), poly(y-valerolactone) poly-lactide, polyglycolide, and a glycolic acid-lactic acid copolymer poly(oxysuc-cinyloxy-1,4-phenylene) and poly(oxyterephthaloyloxy-l,4-phenylene). ...
