Old Acetogens, New Light [PDF]
Acetogens utilize the acetyl-CoA Wood-Ljungdahl pathway as a terminal electron-accepting, energy-conserving, CO2-fixing process. The decades of research to resolve the enzymology of this pathway (1) preceded studies demonstrating that acetogens not only ...

A novel hexameric NADP+‐reducing [FeFe] hydrogenase from Moorella thermoacetica
The acetogenic model organism Moorella thermoacetica reduces CO2 with H2 as an electron donor via the Wood‐Ljungdahl pathway, which requires NADH, NADPH, and reduced ferredoxin as reductants. Whereas NADH and reduced ferredoxin are provided by a previously described electron‐bifurcating FeFe‐hydrogenase, the origin of NADPH remains unknown.

Deletion of nfnAB in Thermoanaerobacterium saccharolyticum and Its Effect on Metabolism [PDF]
NfnAB catalyzes the reversible transfer of electrons from reduced ferredoxin and NADH to 2 NADP+. The NfnAB complex has been hypothesized to be the main enzyme for ferredoxin oxidization in strains of Thermoanaerobacterium saccharolyticum engineered for ...

Mass Spectrometry in the Elucidation of the Glycoproteome of Bacterial Pathogens [PDF]
Presently some three hundred post-translational modifications are known to occur in bacteria in vivo. Many of these modifications play critical roles in the regulation of proteins and control key biological processes.

The Bifunctional Alcohol and Aldehyde Dehydrogenase Gene, adhE, Is Necessary for Ethanol Production in Clostridium thermocellum and Thermoanaerobacterium saccharolyticum [PDF]
Thermoanaerobacterium saccharolyticum and Clostridium thermocellum are anaerobic thermophilic bacteria being investigated for their ability to produce biofuels from plant biomass. The bifunctional alcohol and aldehyde dehydrogenase gene, adhE, is present

Lignite coal burning seam in the remote Altai Mountains harbors a hydrogen-driven thermophilic microbial community [PDF]
Thermal ecosystems associated with underground coal combustion sites are rare and less studied than geothermal features. Here we analysed microbial communities of near-surface ground layer and bituminous substance in an open quarry heated by subsurface ...

Insights into Ionizing-Radiation-Resistant Bacteria S-Layer Proteins and Nanobiotechnology for Bioremediation of Hazardous and Radioactive Waste [PDF]
S-layers are crystalline arrays formed by proteinaceous subunits that cover the outer surface of many different kinds of microorganisms. This “proteinaceous cover” is particularly important in the case of ionizing-radiation-resistant bacteria (IRRB) that

Novel syntrophic populations dominate an ammonia-tolerant methanogenic microbiome [PDF]
Biogas reactors operating with protein-rich substrates have high methane potential and industrial value; however, they are highly susceptible to process failure because of the accumulation of ammonia.
