Abstract: | A group of 13 bacterial species from the rRNA superfamily III were tested for their ability to produce the biodegradable
polyesters poly(3-hydroxybutyrate-co-4-hydroxybutyrate) P(3-HB-co-4-HB)] and poly(3-hydroxybutyrate-co-3-hydroxyvalerate P(3HB-co-3-HV)]. Screening for polyhydroxyalkanoate production was performed on cultures obtained from solid media, rolling cultures
and shaking flasks. All 13 species were able to store a poly(3-hydroxybutyrate) homopolymer, 12 species could produce P(3-HB-co-3-HV) copolymers, but only 9 species accumulated P(3-HB-co-4-HB) copolymers. Similarities in polyhydroxyalkanoate-accumulation behaviour between closely related strains were noted.
