Journal ArticleDOI
Formation of polyesters consisting of medium-chain-length 3-hydroxyalkanoic acids from gluconate by Pseudomonas aeruginosa and other fluorescent pseudomonads.
TL;DR: Results indicated that the formation of PHA depends on a pathway which is distinct from all other known PHA-biosynthetic pathways, and a few species were unable to accumulate poly(hydroxyalkanoic acids) (PHA) at all.
Journal ArticleDOI
Molecular basis for biosynthesis and accumulation of polyhydroxyalkanoic acids in bacteria
Alexander Steinbüchel,Eilert Hustede,Matthias Liebergesell,Ursula Pieper,Arnulf Timm,Henry E. Valentin +5 more
TL;DR: Molecular data will be shown for genes of Alcaligenes eutrophus, purple non-sulfur bacteria, Such as Rhodospirillum rubrum, purple sulfur bacteria, such as Chromatium vinosum, pseudomonads belonging to rRNA homology group I, and for the Gram-positive bacterium Rhodococcus ruber.
Journal ArticleDOI
Cloning and molecular analysis of the poly(3-hydroxyalkanoic acid) gene locus of Pseudomonas aeruginosa PAO1.
TL;DR: Complementation experiments revealed multiple evidence that either polyhydroxyalkanoate synthase is involved in polyhydroylkanoate accumulation from gluconate as well as from octanoate, and two transcriptional start sites resembling Escherichia coli consensus sequences for sigma 54 and sigma 70 promoters were identified experimentally upstream of phaC1Pa.
Journal ArticleDOI
Formation of poly(3-hydroxyalkanoates) by phototrophic and chemolithotrophic bacteria
Matthias Liebergesell,Eilert Hustede,Arnulf Timm,Alexander Steinbüchel,R. Clinton Fuller,Robert W. Lenz,Hans G. Schlegel +6 more
TL;DR: Among 15 strains tested, only Chromatium vinosum strain 1611, C. purpuratum strain BN5500 and Lamprocystis roseopersicina strain 3112 were able to synthesize polyesters containing 3HV with propionate, valerate or heptanoate as carbon source.
Journal ArticleDOI
Formation of blends of various poly(3-hydroxyalkanoic acids) by a recombinant strain of Pseudomonas oleovorans
TL;DR: Recombinant strains of Pseudomonas oleovorans, which harbour the poly(3-hydroxybutyrate)-biosynthetic genes of Alcaligenes eutrophus, accumulated poly(hydroxyalkanoates) which is a blend of the homopolyester poly( 3HB) and of the copolyester poly (3HHx-co-3HO) rather than a random or a block copolyesters of 3HB, 3HH
