Bioplastic (poly-3-hydroxybutyrate) production by the marine bacterium Pseudodonghicola xiamenensis through date syrup valorization and structural assessment of the biopolymer

Bioplastic and Biopolymer Production

Draft genome sequence of Halomonas sp. strain KM-1, a moderately halophilic bacterium that produces the bioplastic poly(3-hydroxybutyrate).

We report the draft genome sequence of Halomonas sp. strain KM-1, which was isolated in Ikeda City, Osaka, Japan, and which produces the bioplastic poly(3-hydroxybutyrate). The total length of the assembled genome is 4,992,811 bp, and 4,220 coding sequences were predicted within the genome. Genes encoding proteins that are involved in the production and depolymerization of poly(3-hydroxybutyrat...

Multiple propionyl coenzyme A-supplying pathways for production of the bioplastic poly(3-hydroxybutyrate-co-3-hydroxyvalerate) in Haloferax mediterranei.

Haloferax mediterranei is able to accumulate the bioplastic poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with more than 10 mol% 3-hydroxyvalerate (3HV) from unrelated carbon sources. However, the pathways that produce propionyl coenzyme A (propionyl-CoA), an important precursor of 3HV monomer, have not yet been determined. Bioinformatic analysis of H. mediterranei genome indicated that t...

Application of the Taguchi Design for Production of Poly(β-hydroxybutyrate) by Ralstonia eutropha

The Taguchi design of experiments was used to test the relative importance of medium components and environmental factors on poly(β-hydroxybutyrate)(PHB) production by Ralstonia eutropha. The optimum condition was obtained as: fructose concentration, 15 g/L; C/N ratio, 7.4; agitation speed 200 rpm; culture time, 40 h; temperature, 25 ° C; seed age, 15 h. At optimu...
