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.
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.
Researchers at the California Institute of Technology have succeeded in modifying bacterial proteins them into powerful enzymes capable of producing silicon-carbon compounds naturally and more efficiently than manmade catalysts.
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.
The scientists have found a way to incorporate the bacterium into a hybrid artificial photosynthesis system capable of synthesizing valuable chemical products. Researchers gifted the bacterium light-harvesting powers by integrating cadmium sulfide nanoparticles.
Cellulose is one of the hardest polysaccharide to hydrolyze. Currently, the conversion of cellulosic materials to renewable energy includes either chemical or biological hydrolysis followed by fermentation of sugars to biofuels. Utility cost of biological- enzymatic hydrolysis is low compared to chemical hydrolysis since it is usually conducted at mild conditions and does not have a corrosion problem. Biological hydrolysis is usually carried out in liquid. However, Solid State hydrolysis is financially feasible due to lower capital investment and lower operating expenses. Most cellulolytic bacteria are anaerobes with a very low growth rate and low enzyme titers.
1,3-butadiene is best-known for its use in the production of rubber to manufacture tyres. It is also used as the basis for producing everyday products, such as raincoats, footwear and casings for electronic equipment. The global market for 1,3 butadiene is expected to reach US$ 33.01 billion by 2020, according to a new study by Grand View Research.
Researchers have discovered how communities of beneficial bacteria form a waterproof coating on the roots of plants, to protect them from microbes that could potentially cause plant disease.
