Abstract This paper presents part of the results obtained during an ICBT short tenn [Pg.115]

Polyhydroxyalkanoates (PHAs) are polyesters formed by many prokaryotic micro-organisms-when unbalanced nutritional conditions are chosen for die (Hoducing cells Up to more than 90% of the cell dry weight can be accounted for as polymer. Besides the homopolyester poly-R-3-hydroxybutanoate, consisting of 3-hydroxybutanoate (3HB) only, two main types of copolyesters can be formed by different microorganisms. The first type of PHAs always contains C3 units in the polymer backbone, but the [Pg.115]
