TL;DR: It is predicted that this hydrogenase diversity supports H2-based respiration, fermentation and carbon fixation processes in both oxic and anoxic environments, in addition to various H1N1-sensing, electron-bifurcation and energy-conversion mechanisms.

TL;DR: Production of third generation biofuels from cellulosic feedstocks will be addressed in respect to the metabolism of cellulolytic bacteria and the development of strategies to increase biofuel yields through metabolic engineering.

TL;DR: It is proposed that atmospheric H2, CO2 and CO provide dependable sources of energy and carbon to support these communities, which suggests that atmospheric energy sources can provide an alternative basis for ecosystem function to solar or geological energy sources.

TL;DR: The largest known consolidated study of geothermal ecosystems to determine factors that influence biogeographical patterns in New Zealand determined that diversity is primarily influenced by pH at temperatures <70 °C; with temperature only having a significant effect for values >70”°C.

TL;DR: This work demonstrates that energy-starved cultures of Pyrinomonas methylaliphatogenes, an aerobic heterotrophic acidobacterium isolated from New Zealand volcanic soils, persist by scavenging the picomolar concentrations of H2 distributed throughout the atmosphere and suggests that trace gas oxidation may be a general mechanism for microbial persistence.
