To provide 4-hydroxybutyryl-CoA for poly(3-hydroxybutyrate-co-4-hydroxybutyrate) formation from glutamate in Escherichia coli, an acetyl-CoA:4-hydroxybutyrate CoA transferase from Clostridium kluyveri, a 4-hydroxybutyrate dehydrogenase from Ralstonia eutropha, a gamma-aminobutyrate:2-ketoglutarate transaminase from Escherichia coli, and glutamate decarboxylases from Arabidopsis thaliana or E. c...

in the present study, four carbon sources were tested for the polyester synthesis of pseudomonas aeruginosa pa01 which is a ubiquitous environmental bacterium and is one of the top three causes of opportunistic human infections. these included linear c8 to c11 carboxylic acids. octanoic acid, nonanoic acid, decanoic acid and undecanoic acid were added to m1 minimal medium to final concentration...

Organ dysfunction is a major cause of morbidity and mortality. Transplantation typically the only definitive cure, challenged by lack sufficient donor organs. Tissue engineering encompasses development biomaterial scaffolds to support cell attachment, proliferation, differentiation, leading tissue regeneration. For efficient clinical translation, forming technology utilized must be suitable for...

Crude glycerol is generated as a by-product during transesterification process and during hydrolysis of fat in the soap-manufacturing process, and poses a problem for waste management. In the present approach, an efficient process was designed for simultaneous production of 0.2 g/L extracellular ε-polylysine and 64.6% (w/w) intracellular polyhydroxyalkanoate (PHA) in the same fermentation broth...

Pseudomonas mendocina NK-01 can synthesize medium-chain-length polyhydroxyalkanoate (PHA(MCL)) and alginate oligosaccharides (AO) simultaneously from glucose under conditions of limited nitrogen. Here, we report the complete sequence of the 5.4-Mbp genome of Pseudomonas mendocina NK-01, which was isolated from farmland soil in Tianjin, China.

Recombinant strains of Ralstonia eutropha and Pseudomonas putida harboring a chimeric polyhydroxyalkanoate (PHA) synthase, which consisted of PHA synthases of Aeromonas caviae and R. eutropha, produced 3-hydroxybutyrate (3HB)-based PHA copolymers comprised of 3-hydroxyhexanoate and 3-hydroxyoctanoate units from dodecanoate (87-97 mol % 3HB), indicating that the chimeric PHA synthase possesses d...

Pseudomonas putida strain CA-3 is an industrial bioreactor isolate capable of synthesizing biodegradable polyhydroxyalkanoate polymers via the metabolism of styrene and other unrelated carbon sources. The pathways involved are subject to regulation by global cellular processes. The draft genome sequence is 6,177,154 bp long and contains 5,608 predicted coding sequences.
