Isolation of Polyhydroxybutyrate (PHB) Producing Bacteria, Optimization of Culture Conditions for PHB production, Extraction and Characterization of PHB

Nepal Journal of Biotechnology, 2018
Polyhydroxybutyrates (PHBs) are energy reserves synthesized by different micro-organisms such as Alcaligenes, Pseudomonas, Staphylococcus, Algae, in excess of carbon and limitation of nutrients like nitrogen.

Enhanced polyhydroxybutyrate (PHB) production by newly isolated rare actinomycetes Rhodococcus sp. strain BSRT1-1 using response surface methodology

Scientific Reports, 2021
Poly-β-hydroxybutyrate (PHB) is a biodegradable polymer, synthesized as carbon and energy reserve by bacteria and archaea. To the best of our knowledge, this is the first report on PHB production by a rare actinomycete species, Rhodococcus pyridinivorans

On the Role and Production of Polyhydroxybutyrate (PHB) in the Cyanobacterium Synechocystis sp. PCC 6803

Life, 2020
The cyanobacterium Synechocystis sp. PCC 6803 is known for producing polyhydroxybutyrate (PHB) under unbalanced nutrient conditions. Although many cyanobacteria produce PHB, its physiological relevance remains unknown, since previous studies concluded ...

Gene expression analysis reveals distinct PHB depolymerization mechanisms and broader involvement of the PHB cycle in Rhodospirillum rubrum growing on acetate and fructose [PDF]

Microbial Cell Factories
Background Rhodospirillum rubrum owns a dynamic poly(3-hydroxybutyrate) (PHB) cycle: During growth PHB is accumulated and subsequently degraded under carbon starvation. Interestingly, this cycle is typically found for acetate grown R.

Physicochemical characterization of polyhydroxybutyrate (PHB) produced by the rare halophile Brachybacterium paraconglomeratum MTCC 13074

Microbial Cell Factories
Background Polyhydroxybutyrate is a biopolymer produced by bacteria and archaea under nitrogen-limiting conditions. PHB is an essential polymer in the bioplastic sector because of its biodegradability, eco-friendliness, and adaptability.

PHB is Produced from Glycogen Turn-over during Nitrogen Starvation in Synechocystis sp. PCC 6803

International Journal of Molecular Sciences, 2019
Polyhydroxybutyrate (PHB) is a polymer of great interest as a substitute for conventional plastics, which are becoming an enormous environmental problem. PHB can be produced directly from CO2 in photoautotrophic cyanobacteria.

No conclusive evidence that difficult general knowledge questions cause a “Google Stroop effect”. A replication study [PDF]

PeerJ, 2020
Access to the digital “all-knowing cloud” has become an integral part of our daily lives. It has been suggested that the increasing offloading of information and information processing services to the cloud will alter human cognition and metacognition in

The effect of inoculum and glucose addition on polyhydroxyalkanoate production by Brevibacterium sp. B45

Menara Perkebunan, 2021
Petroleum-based plastics are the major cause of environmental pollution because the plastics need years to be degraded. The difficulties in handling waste of petroleum-based plastic have motivatedresearchers to produce environmentally friendly plastic ...
