  author={Guo-xia Zhang and Ji-dong Gu},
Degradability of syndiotactic poly ([R]-β-hydroxybutyrate) ( syn -PHB), a chemically synthesized PHB, was investigated in this study by incubation of the polymer films in a soil of northeastern China. During incubation, progressive weight loss of the syn -PHB films and a corresponding decrease of molecular weight were observed over the 90 days of incubation indicating the biodegradation of  syn -PHB  and a random cleavage of the ester bonds. Microorganisms isolated and identified from the…

Plastics from bacteria and for bacteria: poly(beta-hydroxyalkanoates) as natural, biocompatible, and biodegradable polyesters.

Hence, PHB belongs to the family of poly(beta-hydroxyalkanoates), PHA, all of which are usually formed as intracellular inclusions under unbalanced growth conditions. Recently, it became of

Poly(β-hydroxybutyrate) stereoisomers : a model study of the effects of stereochemical and morphological variables on polymer biological degradability

The relative degradability of these PHB stereoisomers was studied with a PHB depolymerase enzyme isolated from Penicillium funiculosum, and this enzyme has been shown to catalyze the hydrolysis of (R)-PHB, but does not show activity for the enantiomeric substrate (S-PHB.

Syndiospecific ring-opening polymerization of .beta.-butyrolactone to form predominantly syndiotactic poly(.beta.-hydroxybutyrate) using tin(IV) catalysts

Bis(tri-n-butyltin) oxide ((n-Bu 3 Sn) 2 O), bis(triphenyltin) oxide (Ph 3 Sn) 2 O), and di-β-butyltin dimethoxide (Sn(n-Bu) 2 (OCH 3 ) 2 ) were all shown to catayze the syndiospecific polymerization

Occurrence, metabolism, metabolic role, and industrial uses of bacterial polyhydroxyalkanoates.

The physiological functions of PHB as a reserve material and in symbiotic nitrogen fixation and its presence in bacterial plasma membranes and putative role in transformability and calcium signaling are also considered.

Methanogenic Degradation of Poly(3-Hydroxyalkanoates)

Two polymeric compounds were fermented to methane and carbon dioxide within 16 days by an anaerobic sewage sludge consortium, and between 83 and 96% of the substrate carbon was transformed to methane or carbon dioxide.

Cellulose acetate biodegradability upon exposure to simulated aerobic composting and anaerobic bioreactor environments

The relatively small CA film weight loss observed in the poisoned control test vessels allows the conclusion that CA film erosion during the composting exposures resulted, at least in part, from biologically mediated processes.

Effect of environmental parameters on the degradability of polymer films in laboratory-scale composting reactors

Previous research in our laboratory reported a convenient laboratory-scale composting test method to study the weight loss of polymer films in aerobic thermophilic (53°C) reactors maintained at a 60%

Susceptibility of electronic insulating polyimides to microbial degradation

We used electrochemical impedance spectroscopy (EIS) to investigate microbial degradation of polyimides used as insulators in electronic packaging. The microbial inoculum was a fungal consortium

Cloning, nucleotide sequence, and expression in Escherichia coli of the gene for poly(3-hydroxybutyrate) depolymerase from Alcaligenes faecalis

Comparison of the deduced amino terminus with that obtained from sequence analysis of the purified protein indicated that poly(3-hydroxybutyrate) depolymerase exists as a 488-amino-acid precursor with a signal peptide of 27 amino acids, which is similar to that of A. faecalis T1.
