Novel polyhydroxyalkanoate copolymers produced in Pseudomonas putida by metagenomic polyhydroxyalkanoate synthases [PDF]

Applied Microbiology and Biotechnology, 2016
Bacterially produced biodegradable polyhydroxyalkanoates (PHAs) with versatile properties can be achieved using different PHA synthases (PhaCs). This work aims to expand the diversity of known PhaCs via functional metagenomics and demonstrates the use of these novel enzymes in PHA production.

First evidence for temperature’s influence on the enrichment, assembly, and activity of polyhydroxyalkanoate-synthesizing mixed microbial communities

Frontiers in Systems Biology
Polyhydroxyalkanoates (PHA) are popular biopolymers due to their potential use as biodegradable thermoplastics. In this study, three aerobic sequencing batch reactors were operated identically except for their temperatures, which were set at 15 °C, 35 °C,

Controle da biossíntese de poli-hidroxialcanoatos bacterianos através do fluxo de substratos Control of the biosynthesis of bacterial polyhydroxyalkanoates through the flux of substrates

Química Nova, 2007
Manipulation of the flux of substrates was utilized to control the amount of 3-hydroxyvalerate and 3-hydroxy-4-pentenoate produced by Burkohlderia sp. The 3HV production rate was directly proportional to the propionic acid uptake rate with the last one ...
