Advances in Polyhydroxyalkanoate (PHA) Production
This editorial paper provides a synopsis of the contributions to the Bioengineering special issue "Advances in Polyhydroxyalkanoate (PHA) Production". It illustrates the embedding of the issue's individual research articles in the current global research and development landscape related to polyhydroxyalkanoates (PHA). The article shows how these articles are interrelated to each other, reflect...
متن کاملProduction of Pha by Recombinant Organisms
Polyhydroxyalkanoates (PHA) are biodegradable, thermoplastic polyesters produced from renewable carbon sources by a number of bacteria. However, their application is limited by high production costs. One of the strategies aimed to reduce their costs is the development of recombinant strains able to utilize different carbon sources. Many bacteria are naturally capable of accumulating biopolyeste...
متن کاملPolyhydroxyalkanoate (PHA) production from tapioca industrial wastewater treatment: Influence of operating conditions on PHA content
The aims of these experiments were treating tapioca processing waste water to produce polyhydroxyalkanoates (PHAs) and removal of chemical oxygen demand (COD). The experiments were conducted in a sequencing batch reactor with a volume of 6 L. The entire experimental condition was anaerobic-aerobic-anaerobic. Experiment 1, 2 and 3 had the first 2 h for feeding time while Experiment 4 had 3 h. Th...
متن کاملUse of Lignocellulosic Materials for PHA Production
Life of modern civilization is accompanied by accumulation of huge amounts of non-degradable solid waste materials. A major portion of this resistant waste is represented by synthetic polymers of petrochemical origin. The accumulation of plastic wastes has become a very important environmental issue1. Conventional synthetic polymers are problematic not only because of their long decomposition t...
متن کاملPolyhydroxyalkanoate (PHA) accumulation in sulfate-reducing bacteria and identification of a class III PHA synthase (PhaEC) in Desulfococcus multivorans.
Seven strains of sulfate-reducing bacteria (SRB) were tested for the accumulation of polyhydroxyalkanoates (PHAs). During growth with benzoate Desulfonema magnum accumulated large amounts of poly(3-hydroxybutyrate) [poly(3HB)]. Desulfosarcina variabilis (during growth with benzoate), Desulfobotulus sapovorans (during growth with caproate), and Desulfobacterium autotrophicum (during growth with ...
