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 کاملHydrogen metabolism in aerobic hydrogen-oxidizing bacteria.
A survey on organisms able to use molecular hydrogen as electron donor in the energy-yielding process is presented. In the group of the aerobic hydrogen-oxidizing bacteria so far two types of hydrogenases have been encountered, a NAD-reducing, soluble enzyme (H2 : NAD oxidoreductase) and a membrane-bound enzyme unable to reduce pyridine nucleotides. With respect to the distribution of both type...
متن کاملPeptidohydrolases of Soybean Root Nodules
Nodule extracts prepared from Glycine max var Woodworth possessed endopeptidase, aminoptidase, and carboxypeptidase actiities. Three distinct endopeptidase activities could be resolved by disc-gel electrophoresis at pH 8.8. According to their order of increasing electrophoretic mobility, the first of these enzymes hydrolyzed azocasein and n-benzoyl-LLeu-p8-naphthylamide, while the second hydrol...

متن کاملKinetic mechanism of the hydrogen-oxidizing hydrogenase from soybean nodule bacteroids.
The kinetic mechanism of the unidirectional H2-oxidizing hydrogenase from soybean nodule bacteroids has been investigated with highly purified enzyme. Measurements of the Km for H2 vary from 0.97 to 2.6 microM, and the Km for methylene blue varies from 6 to 17 microM. With H2 and methylene blue as substrates, the initial velocity patterns are intersecting. High levels of methylene blue are inhi...
