چکیده

Biopolymers are a promising alternative to petroleum-based plastic raw materials. They bio-based, non-toxic and degradable under environmental conditions. In addition the homopolymer poly(3-hydroxybutyrate) (PHB), there number of co-polymers that have broad range applications easier process in comparison PHB. The most prominent representative from this group bio-copolymers is poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV). article, we show new kinetic model describes PHBV production fructose propionic acid Cupriavidus necator (C. necator). developed used analyze effects parameter variations such as CO2 amount exhaust gas feed rate. presented valuable tool improve microbial process. Due coupling online measurements biomass production, has potential predict composition current yield ongoing

Production of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) in recombinant Corynebacterium glutamicum using propionate as a precursor.

Lipopolysaccharides free P[3-hydroxybutyrate (3HB)-co-3-hydroxyvalerate (3HV)] production was achieved using recombinant Corynebacterium glutamicum harboring polyhydroxyalkanoate (PHA) biosynthetic genes from Ralstonia eutropha. Cells grown on glucose with feeding of propionate as a precursor of 3HV unit accumulated 8-47wt% of P(3HB-co-3HV). The 3HV fraction in the copolymer was varied from 0 t...

Production and characterization of biodegradable terpolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-4-hydroxybutyrate) by Alcaligenes sp. A-04.

The production of the terpolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-4-hydroxybutyrate), P(3HB-co-3HV-co-4HB), by Alcaligenes sp. A-04 was investigated to determine the superior biodegradable polymer properties over those of poly(3-hydroxybutyrate), P(3HB), and its copolymers. The highest terpolymer content of 68% (w/w) was produced by Alcaligenes sp. A-04 at 60 h by shake-flask cult...
