Regulating bacteria’s metabolism could pave way for increased biofuel production [Full subscriber]

Researchers at University of California Riverside (UCR) and Pacific Northwest National Laboratory (PNNL) have used mathematical and computational modelling, artificial intelligence algorithms and experiments showing that bacteria have failsafe mechanisms preventing them from producing too many metabolic intermediates.

Global ‘soil atlas’ reveals handful of bacteria dominate the Earth’s soil [Registered]

Soil bacteria play key roles in regulating terrestrial carbon dynamics, nutrient cycles, and plant productivity. However, the natural histories and distributions of these organisms remain largely undocumented. An extensive study by an international team of researchers has found that only a small percentage of bacterial species are both common and abundant in soils around the world.

Cyborg bacteria effective in producing useful chemicals from sunlight [Registered]

Researchers at the University of California Berkeley may have introduced a new era in artificial photosynthesis. They’ve devised a way to cover bacteria with cadmium sulphide semiconductor nanocrystals to breakdown CO2 into acetic acid, a potential feedstock for biosynthesis of fuels and plastics.

Hydrogen biofuel “nano-reactor” created from bacteria and viruses [Registered]

The researchers developed “P22-Hyd” by modifying an enzyme and placing it within a protective protein shell, a “capsid”, from a bacterial virus. The strengthened biological catalyst is 150 times more efficient than the original enzyme.
