Hydrogen Oxidizing Bacteria as Poly(hydroxybutyrate) Producers
Batch culture of Ralstonia eutropha using the recycled gas closed circuit culture system was conducted in order to develop a practical fermentation system for industrial autotrophic culture for poly (hydroxybutrate) production. The gas phase of the culture system consisted of substrate gas so that gases in this culture could be recycled as long as the amount of the gas consumed would be repleni...
متن کاملRole of hydrogen in the activation and regulation of hydrogen oxidation by the soluble hydrogenase from Alcaligenes eutrophus H16.
The activation kinetics of the H2-oxidizing activity of the soluble hydrogenase from Alcaligenes eutrophus H16 were investigated. Activation with Na2S2O4 plus 101 kPa H2 resulted in a rapid increase in activity over 1 h and constant activity after 3 h incubation. Less-stable activations were achieved if enzyme was incubated with Na2S2O4 under 1 kPa H2 or 101 kPa N2. The enzyme could also be par...
متن کاملThe Alcaligenes eutrophus H16 hoxX gene participates in hydrogenase regulation.
Nucleotide sequence analysis revealed a 1,791-bp open reading frame in the hox gene cluster of the gram-negative chemolithotroph Alcaligenes eutrophus H16. In order to investigate the biological role of this open reading frame, we generated an in-frame deletion allele via a gene replacement strategy. The resulting mutant grew significantly more slowly than the wild type under lithoautotrophic c...
متن کاملOccurrence of polyhydroxyalkanoic acid granule-associated proteins related to the Alcaligenes eutrophus H16 GA24 protein in other bacteria.
Fifty different polyhydroxyalkanoic acid (PHA)-accumulating bacterial strains were investigated for the occurrence of phasin proteins bound to PHA granules and related to the GA24 protein of Alcaligenes eutrophus H16, by isolating PHA granules and Western blot analysis of granule-associated proteins employing antibodies raised against the GA24 protein. It could be demonstrated that th PHA granu...
