The Organellar Genome and Metabolic Potential of the Hydrogen-Producing Mitochondrion of Nyctotherus ovalis
It is generally accepted that hydrogenosomes (hydrogen-producing organelles) evolved from a mitochondrial ancestor. However, until recently, only indirect evidence for this hypothesis was available. Here, we present the almost complete genome of the hydrogen-producing mitochondrion of the anaerobic ciliate Nyctotherus ovalis and show that, except for the notable absence of genes encoding electr...
متن کاملIs myelin a mitochondrion?
It has been hypothesized that myelin acts like a mitochondrion, generating ATP across the membranes of its sheath. By calculating the proton motive force across the myelin membrane based on known values for the pH and membrane potential of the oligodendrocyte, we find that insufficient energy could be harvested from proton flow across the myelin membrane to synthesize ATP. In fact, if the respi...
متن کاملMitochondrion.
Diverse biological data may be used to create illustrations of molecules in their cellular context. I describe the scientific results that support a recent textbook illustration of a mitochondrion. The image magnifies a portion of the mitochondrion by one million times, showing the location and form of membranes and individual macromolecules, revealing the molecular basis of its role in energy ...
متن کاملPiezoelectric Bimorph Cantilever for Vibration-Producing-Hydrogen
A device composed of a piezoelectric bimorph cantilever and a water electrolysis device was fabricated to realize piezoelectrochemical hydrogen production. The obvious output of the hydrogen and oxygen through application of a mechanical vibration of ~0.07 N and ~46.2 Hz was observed. This method provides a cost-effective, recyclable, environment-friendly and simple way to directly split water ...
متن کاملPretreatment to Increase Hydrogen Producing Bacteria (HPB)
This Chapter focuses on the investigation of an easy and efficacious method of obtaining a hydrogen-producing bacteria (HPB) culture to the detriment of hydrogen-consuming bacteria (HCB), such as methanogens and homoacetogenic bacteria. Although the use of mixed microflora is more viable from both the practical and biological points of view, important limitations arise from the co-activity of H...
