Alcaligenes eutrophus mutant strain R3, which is a spontaneous revertant to prototrophy of an isoleucine-auxotrophic mutant of the wild-type strain H16, accumulated a copolyester consisting of 3-hydroxybutyric acid (3HB) as main constituent and of 3hydroxyvaleric acid (3HV), i.e. poly(3HB-co-3HV), a
High cell density fed-batch fermentation of Al-replacement applications (Brandl et al., 1990; Doi, caligenes eutrophus was carried out for the production 1990). Currently, ZENECA Bio Products produces coof poly(3-hydroxybutyrate) (PHB) in a 60-L fermentor. ## polymers of PHB/PHV through a bacterial
Production of copolymer consisting of 3-hydroxybutyrate and 3-hydroxyvalerate [poly(3HB-co-3HV)] by fed-batch culture ofAlcaligenes sp. SH-69 was investigated using glucose as a sole carbon source. Synthesis of poly(3HB-co-3HV) during the polymer accumulation stage was favored under dissolved oxygen
