Crystallization kinetics of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)/cellulose nanowhiskers composites

Carbohydrate Polymers, 2012
In this study, biodegradable poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films with 1.2-4.6 wt% of cellulose nanowhiskers (CNWs) were manufactured by solution casting using N,N-dimethylformide (DMF) as the solvent. Crystallization behaviors of PHBV/CNW composites were studied under isothermal conditions using differential scanning calorimetry ...

Targeted poly(3-hydroxybutyrate-co-3-hydroxyvalerate) bioplastic production from carbon dioxide

Bioresource Technology, 2018
A microbial production process was developed to convert CO2 and valeric acid into tailored poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) bioplastics. The aim was to understand microbial PHBV production in mixotrophic conditions and to control the monomer distribution in the polymer.

Surface grafting of cellulose nanocrystals with poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

Carbohydrate Polymers, 2014
Chemically modified cellulose nanocrystals (CNCs) were synthesized by grafting poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) onto CNCs via homogeneous acylation reaction between N,N-dimethyl formamide (DMF) by using toluene diisocyanate (TDI) as coupling agent and dibutyltin dilaurate as catalyst. The resulting copolymers were studied by using (1)

Biosynthesis of poly(3-hydroxybutyrate- co -3-hydroxyvalerate) by Halogeometricum borinquense strain E3

International Journal of Biological Macromolecules, 2015
Polyhydroxyalkanoates (PHA's) can be a key solution for pollution problems caused by plastics derived from petrochemical sources. Extremely halophilic archaeon Halogeometricum borinquense strain E3 showed maximum PHA accumulation of 73.51 ±1.7% (wt/wt) of cell dry weight (CDW) with 2% glucose.

Co-crystallization of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

Journal of Materials Science, 1992
A combined study of X-ray diffraction, differential scanning calorimetry and density measurements in copolymers of 3-hydroxybutyrate and 3-hydroxyvalerate is presented. It is shown that the unit cell volume expands linearly with the comonomer content in the polymer.

Isothermal crystallization of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

European Polymer Journal, 2003
Isothermal crystallization behavior of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) was investigated by means of differential scanning calorimetry and polarized optical microscopy (POM). The Avrami analysis can be used successfully to describe the isothermal crystallization kinetics of PHBV, which indicates that the Avrami exponent n = 3 is good

Fabrication of chitin/poly(3-hydroxybutyrate-co-3-hydroxyvalerate) hydrogel scaffold

Carbohydrate Polymers, 2012
Regeneration of skin after a large area wound or burn is often difficult without the aid of a scaffold. In this work we developed a 3D macroporous chitin/poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) hydrogel blend by normal solution chemistry and lyophilized it to get the scaffold.

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) production by Haloarchaeon Halogranum amylolyticum

Applied Microbiology and Biotechnology, 2015
Haloarchaea is an important group of polyhydroxyalkanoate (PHA)-accumulating organisms. However, few promising haloarchaeal species for economical and efficient PHA production have been reported. Here, we first discovered that Halogranum amylolyticum TNN58 could efficiently accumulate poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with a high 3 ...
