Modeling pure culture heterotrophic production of polyhydroxybutyrate (PHB)
Bioresource Technology, 2014In this contribution a mechanistic model describing the production of polyhydroxybutyrate (PHB) through pure-culture fermentation was developed, calibrated and validated for two different substrates, namely glucose and waste glycerol. In both cases, non-growth-associated PHB production was triggered by applying nitrogen limitation.

Phage-based extraction of polyhydroxybutyrate (PHB) produced from synthetic crude glycerol
Science of The Total Environment, 2016Polyhydroxybutyrate (PHB), a biodegradable plastic, is an attractive alternative to traditional petrochemical-derived plastics. However, its production is expensive due to high feedstock and extraction costs. As bacteriophages are natural predators to bacteria and specific to their hosts, bacteriophages offer a new and unique means to release PHB from ...

Crystallization behavior of polyhydroxybutyrate (PHB)
AIP Conference Proceedings, 2016Polyhydroxybutyrate (PHB) belongs to the family of polyhydroxyalkanoates and is both, biobased and biodegradable. Due to its linear chain structure, PHB is highly crystalline and has a melting temperature close to its decomposition temperature. Pure PHB crystallizes very slowly, so that the use for some technical applications is not commercially viable.

Applied Microbiology and Biotechnology, 2018
The biodegradation of polyhydroxybutyrate (PHB) has been broadly investigated, but studies typically focus on a single strain or enzyme and little attention has been paid to comparing the interaction of different PHB depolymerase (PhaZ)-producing strains with this biopolymer.

Flame retardancy of sustainable polylactic acid and polyhydroxybutyrate (PLA/PHB) blends
International Journal of Biological Macromolecules, 2023Nowadays, development of new biobased/biodegradable polymers from biological resources is of great interest from a sustainability standpoint. Polyhydroxybutyrate (PHB) and polylactic acid (PLA) are two biopolymers obtained from renewable resources. In this study, the flame-retardant effect of a newly developed flame retardant (FR) based on melamine in ...

On-chip THz spectroscopy of Polyhydroxybutyrate (PHB) powder
2013 38th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2013We recently demonstrated terahertz radiation from joule-heated Single Wall Carbon Nanotubes (SWCNTs) whose main defining feature was a broad frequency spectrum mediated by an antenna [1]. In this work, we use such a source in an integrated THz circuit to demonstrate the feasibility of an on-chip spectroscopy system through measurements on ...

Embolization with Polyhydroxybutyrate (PHB) Microspheres: In-Vivo Studies
Journal of Bioactive and Compatible Polymers, 1999In this study polyhydroxybutyrate (PHB), produced by a methanol-utilizing bacteria, was used to prepare microspheres in the 120-200 μm size range for embolization. A solvent evaporation technique was utilized to obtain microspheres in which methylene chloride, distilled water and polyvinyl alcohol were used as the solvent, precipitation medium and ...

Thermal and rheological properties of modified polyhydroxybutyrate (PHB)
Polymer Engineering & Science, 2019With the discussion of sustainability and the increased environmental awareness, the biopolymer poly‐β‐hydroxybutyrate (PHB) has gained more and more attention in recent years. It derives from renewable sources and can degrade in different environments to carbon dioxide and water.

Spherulitic Growth Rate of Blends of Polyhydroxybutyrate (PHB) with Oligomeric Atactic PHB-diol
Journal of Macromolecular Science, Part B, 2011Spherulitic growth rates of blends of polyhydroxybutyrate (PHB) with oligomers of atactic R,S-PHB-OH (Mn = 610, 910, and 2670 g/mol), as well as atactic R,S-PHB (Mn = 30 000 g/mol), were investigated by polarized light optical microscopy in the range from 50°C to 110°C.

Dynamics and operation analysis of the PHB (polyhydroxybutyrate) fermentation
2015Abstract PHB (polyhydroxybutyrate) is a biodegradable polymer that is gaining importance worldwide due to their applications. In this study, the PHB fermentation process is studied using sucrose as substrate and Azohydromonas australica as strain. A dynamic model of the isothermal reactor fermentation is used to calculate mainly product yield and ...
