Active Intermediates of Polyhydroxyalkanoate Synthase from Aeromonas caviae in Polymerization Reaction [PDF]
Biomacromolecules, 2012 Polyhydroxyalkanoate (PHA) synthase from Aeromonas caviae FA440 (PhaC(Ac), BAA21815) is one of the most valuable PHA synthase, because of its function to synthesize a practical bioplastic, poly[(R)-3-hydroxybutyrate-co-(R)-3-hydroxyhexanoate] [P(3HB-co-3HHx)].

A Novel Link Between Electron Transport Chain Modulation and mcl-PHA Production in Pseudomonas aeruginosa 5300 Using Azide as a Modulator. [PDF]
Environ Microbiol RepThe oleic acid and azide inhibited the cytochrome c oxidase activity in Pseudomonas aeruginosa MCC 5300, shifting the electron flux towards bd‐oxidase. This resulted in more NADH consumption to maintain the proton gradient for energy generation. The rapid depletion of NADH triggered high mcl‐PHA accumulation.

Journal of Microbiology and Biotechnology, 2018 Pseudomonas fluorescens KLR101 was found to be capable of producing polyhydroxyalkanoate (PHA) using various sugars and fatty acids with carbon numbers ranging from 2 to 6. The PHA granules consisted mainly of a poly(3-hydroxybutyrate) homopolymer and/or poly(3-hydroxybutyrate-co-3-hydroxyvalerate) copolymer. Genomic DNA of P.

The alternative sigma factor, σS, affects polyhydroxyalkanoate metabolism in Pseudomonas putida [PDF]
, 2008 To determine whether the stationary sigma factor, σS, influences polyhydroxyalkanoate metabolism in Pseudomonas putida KT2440, an rpoS-negative mutant was constructed to evaluate polyhydroxyalkanoate accumulation and expression of a translational fusion ...
