Polyhydroxyalkanoates are essential for maintenance of redox state in the Antarctic bacterium Pseudomonas sp. 14-3 during low-temperature adaptation
(Springer Tokyo, 2009-01)
Polyhydroxyalkanoates (PHAs) are highly reduced bacterial storage compounds that increase fitness in changing environments. We have previously shown that phaRBAC genes from the Antarctic bacterium Pseudomonas sp. 14-3 are ...
Strategy for biological co-production of levulinic acid and polyhydroxyalkanoates by using mixed microbial cultures fed with synthetic hemicellulose hydrolysate
(Elsevier, 2020-05)
Hemicellulose hydrolysates (HH), which could be an interesting carbon source to feed mixed microbial cultures (MMC) able to accumulate high value-added compounds. This research focused on the evaluation of a culture strategy ...
The polyhydroxyalkanoate genes of a stress resistant Antarctic Pseudomonas are situated within a genomic island
(Academic Press Inc Elsevier Science, 2007-11)
Pseudomonas sp. 14-3 is an Antarctic bacterium that shows high stress resistance in association with high polyhydroxybutyrate (PHB) production. In this paper genes involved in PHB biosynthesis (phaRBAC) were found within ...
Glycogen formation by Rhodococcus species and the effect of inhibition of lipid biosynthesis on glycogen accumulation in Rhodococcus opacus PD630
(Oxford University Press, 2010-11)
Members of the genus Rhodococcus were investigated for their ability to produce glycogen during cultivation on gluconate or glucose. Strains belonging to Rhodococcus ruber, Rhodococcus opacus, Rhodococcus fascians, Rhodococcus ...
Reporting key features in cold-adapted bacteria
(MDPI AG, 2018-03)
It is well known that cold environments are predominant over the Earth and there are a great number of reports analyzing bacterial adaptations to cold. Most of these works are focused on characteristics traditionally ...
Microstructural Behaviors of Matrices Based on Polylactic Acid and Polyhydroxyalkanoates
(American Chemical Society, 2018-09)
Individual films of polyhydroxyalkanoates (PHA) and polylactic acid (PLA) and their blends were developed by solvent casting. PHA was obtained from activated sludges from a wastewater-treatment system at a laboratory scale. ...
Modeling the bioconversion of starch to P(HB-co-HV) optimized by experimental design using Bacillus megaterium BBST4 strain
(Taylor & Francis Ltd, 2018-01-02)
Poly(hydroxybutyrate-co-hydroxyvalerate) (P(HB-co-HV)) is a prominent biopolymer as a potential candidate for use in the biomedical area. Several Bacillus spp. strains show promising characteristics in the use of several ...
Design and optimization of poly(hydroxyalkanoate)s production plants using alternative substrates
(Elsevier, 2019-10)
In this work, we propose a Mixed Integer Nonlinear Programming (MINLP) model to determine the optimal design of a poly(hydroxyalkanoate)s (PHAs) production plant configuration. The superstructure based optimization model ...
Pseudomonas extremaustralis sp. nov. a polyhydroxybutyrate-producer isolated from Antarctic environments
(Springer, 2009-12)
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 ...
Improved intracellular PHA determinations with novel spectrophotometric quantification methodologies based on Sudan black dye
(Elsevier Science, 2018-05)
The presence of intracellular polyhydroxyalkanoates (PHAs) is usually studied using Sudan black dye solution (SB). In a previous work it was shown that the PHA could be directly quantified using the absorbance of SB fixed ...
