Polyhydroxybutyrate (PHB) is a carbon reserve found in some bacteria, and under nutrient limiting conditions accumulates intracellularly in the form of inclusion bodies. These inclusions contain proteins, and the PHI3 within the inclusions exists in an amorphous state. In this study a procedure to recover native PHB inclusions was developed, and the isolated inclusions were characterized using ...

Polyhydroxybutyrate Homopolymers (PHB) were produced by transgenic yeasts Saccharomyces cerevisiae INVSc1/PHA1 and Schizosaccharomyces pombe Q01/PHB equipped in their cytoplasm and chromosome with the phaABC operon of the PHA biosynthetic pathway of Ralstonia eutropha, respectively. Re The polyesters were purified and physically characterized by Differential Scanning Calorimetry (DSC) and Infra...

Polyhydroxyalkanoates (PHA) are good alternatives on account of biocompatible and biodegradable properties to produce materials as scaffolds for engineered tissues. Polyhydroxybutyrate (PHB) which is a member of polyhydroxyalkanoate family have been widely used as a biomaterial for in vitro and in vivo studies due to its unique properties such as improved flexibility and processability. In this...

This study was focused on the polyhydroxybutyrate (PHB) accumulation property of Bacillus aryabhattai isolated from environment. Twenty-four polyhydroxyalkanoate (PHA) producers were screened out from sixty-two environmental bacterial isolates based on Sudan Black B colony staining. Based on their PHA accumulation property, six promising isolates were further screened out. The most productive i...
