Hydrogen-fueled CO2 reduction using oxygen-tolerant oxidoreductases

Frontiers in Bioengineering and Biotechnology, 2023
Hydrogen gas obtained from cheap or sustainable sources has been investigated as an alternative to fossil fuels. By using hydrogenase (H2ase) and formate dehydrogenase (FDH), H2 and CO2 gases can be converted to formate, which can be conveniently stored ...

Evaluation of polyhydroxyalkanoate (PHAs) production with a bacterial isolate using cassava flour hydrolysates as an alternative substrate

Dyna, 2019
In the production of polyhydroxyalkanoates (PHA), the costs of the process are mainly associated with the carbon source and most of the production studies are carried out with commercial strains. In this study, PHA production was evaluated using a strain,

Continuous feeding strategy for polyhydroxyalkanoate production from solid waste animal fat at laboratory‐ and pilot‐scale

Microbial Biotechnology, Volume 16, Issue 2, Page 295-306, February 2023., 2023
Abstract Bioconversion of waste animal fat (WAF) to polyhydroxyalkanoates (PHAs) is an approach to lower the production costs of these plastic alternatives. However, the solid nature of WAF requires a tailor‐made process development. In this study, a double‐jacket feeding system was built to thermally liquefy the WAF to employ a continuous feeding ...

IN SILICO ANALYSIS OF PHAG-LIKE PROTEIN IN RALSTONIA EUTROPHA H16, POTENTIALLY INVOLVED IN POLYHYDROXYALKANOATES SYNTHESIS

Revista Politécnica, 2019
Polyhydroxyalkanoates (PHA) are synthesised by bacteria as carbon storage material. The protein PhaG directs carbon from non-related carbon sources such as glycerol, metabolised through fatty acid de novo synthesis (FAS) pathway, with PHA synthesis.

Rational engineering of natural polyhydroxyalkanoates producing microorganisms for improved synthesis and recovery

Microbial Biotechnology, Volume 16, Issue 2, Page 262-285, February 2023., 2023
This review describes the attempts to rationally engineering the cellular operation of several microbes to elevate PHA production on specific substrates and waste products. We also delve into genome reduction, morphology, and redox cofactor engineering to boost PHA biosynthesis.
