High Polyhydroxybutyrate Production in Pseudomonas extremaustralis Is Associated with Differential Expression of Horizontally Acquired and Core Genome Polyhydroxyalkanoate Synthase Genes
(Public Library of Science, 2014-06)
Pseudomonas extremaustralis produces mainly polyhydroxybutyrate (PHB), a short chain length polyhydroxyalkanoate (sclPHA) infrequently found in Pseudomonas species. Previous studies with this strain demonstrated that PHB ...
Polyhydroxyalkanoate (PHA): Review of synthesis, characteristics, processing and potential applications in packaging
(Budapest University of Technology and Economics, 2014-06)
Polyhydroxyalkanoates (PHAs) are gaining increasing attention in the biodegradable polymer market due to their promising properties such as high biodegradability in different environments, not just in composting plants, ...
Properties of Polyhydroxyalkanoate Granules and Bioemulsifiers from Pseudomonas sp. and Burkholderia sp. Isolates Growing on Glucose
A Burkholderia and Pseudomonas species designated as AB4 and AS1, respectively, were isolated from soil containing decomposing straw or sugar cane bagasse collected from Brazil. This study sought to evaluate the capacities ...
Pseudomonas extremaustralis sp. nov. a polyhydroxybutyrate-producer isolated from Antarctic environments
A Gram-negative, mobile, rod-shaped, non-spore-forming bacterium (strain 14-3T) was isolated from a temporary pond in Antarctica. On the basis of 16S rRNA gene sequence similarity, strain 14-3T was shown to belong to the ...
Enzymatic recovery and purification of polyhydroxybutyrate produced by Ralstonia eutropha
(Elsevier Science BvAmsterdamHolanda, 2006)
Assessment of different plasticizer – polyhydroxyalkanoate mixtures to obtain biodegradable polymeric films
The elaboration of films from biodegradable polymer polyhydroxybutyrate was studied with 4 main plasticizers at variable concentrations: polyethyleneglycol, lauric acid, glycerol and epoxidized soy bean oil. An evaluation ...
Bacterial polyhydroxybutyrate for electrospun fiber production
Nano- and microfibers obtained by electrospinning have attracted great attention due to its versatility and potential for applications in diverse technological fields. Polyhydroxyalkanoates (PHAs) are biopolymers synthesized ...
Cassava wastewater as carbon source for the polyhydroxybutyrate production by Azotobacter vinelandii CCT 2841
The polyhydroxybutyrate (PHB) is also known as bioplastic, have thermoplastic properties and performance characteristics similar to conventional plastics. However, bioplastics are easily degraded by the microorganisms ...
