Cyanobacterial Polyhydroxybutyrate (PHB): Screening, Optimization and Characterization

In modern life petroleum-based plastic has become indispensable due to its frequent use as an easily available and a low cost packaging and moulding material. However, its rapidly growing use is causing aquatic and terrestrial pollution. Under these circumstances, research and development for biodegradable plastic (bioplastics) is inevitable. Polyhydroxybutyrate (PHB), a type of microbial polye...

Improved polyhydroxybutyrate (PHB) production in transgenic tobacco by enhancing translation efficiency of bacterial PHB biosynthetic genes.

Polyhydroxybutyrate [P(3HB)] was produced in the transgenic tobacco harboring the genes encoding acetoacetyl-CoA reductase (PhaB) and polyhydroxyalkanoate synthase (PhaC) from Ralstonia eutropha (Cupriavidus necator) with optimized codon usage for expression in tobacco. P(3HB) contents in the transformants (0.2mg/g dry cell weight in average) harboring the codon-optimized phaB gene was twofold ...

A Closer Look on the Polyhydroxybutyrate- (PHB-) Negative Phenotype of Ralstonia eutropha PHB-4

The undefined poly(3-hydroxybutyrate)- (PHB-) negative mutant R. eutropha PHB-4 was generated in 1970 by 1-nitroso-3-nitro-1-methylguanidine (NMG) treatment. Although being scientific relevant, its genotype remained unknown since its isolation except a recent first investigation. In this study, the mutation causing the PHA-negative phenotype of R. eutropha PHB-4 was confirmed independently: seq...

Studies on PHB (Polyhydroxybutyrate) degradation by some species of Aspergillus

PHB degradation capabilities of seven species of Aspergillus namely Aspergillus niger, Aspergillus flavus, Aspergillus ochraceus, Aspergillus nidulans, Aspergillus terreus, Aspergillus fumigatus and Aspergillus parasiticus on the polymer produced by Rhodospseudomonas palustris KU003 were assayed . Among all the fungi investigated, the ability of A.niger to utilize the biopolymer was the highest...
