(e.g., cellulosic biomass or glycerin-containing biomass) to produce a fermentation byproduct; and a second biocatalyst comprising an electricigen (e.g., Geobacter sulfurreducens) capable of transferring substantially all the electrons in the fermentation byproduct (e.g., hydrogen, one or more ...
Primary producers are a basic part of an ecosystem. They can be thought of as the first and most important step in the food chain. Along with decomposers, they make up the base of a food web and together their populations number more than any other part of the web. Primary producers are...
Fuel ethanol is a renewable liquid transportation fuel widely used in the United States and Brazil that is expected to become a dominant renewable biofuel in the transport sector within the next 20 years [42,56,123]. Most ethanol is currently made from maize (US) or sugar cane (Brazil), b...
Studies in the literature that consider the effects of both ecologically responsible criteria and productivity-boosting criteria in the same growth framework for developing nations are insufficient. These industries frequently focus on the electricity that is produced using traditional fuels; therefore, it ...
Energy storage and the balance of producers and decomposers in ecological systems The two major commercial methods for making gypsum board water resistant are through incorporation of hydrocarbon wax emulsions or polymethylhydrogensiloxa... OLSON,JS - 《Ecology》 被引量: 4535发表: 1963年 ...
The formation of the universe, commonly referred to as the “Big Bang,” primarily formed the elements hydrogen, helium, and a little lithium. All the other chemical elements, including the majority of lithium, are formed in stars. Classical novae are a class of stars consisting o...
The cell may be a leadsulphuric acid accumulator, a silver-zinc battery with an alkaline electrolyte, or a hydrogenoxygen fuel cell with an alkaline or sulphuric acid electrolyte. The ionic polymers should contain at least one ionic group per 6 monomer residues or per 12 chain carbon atoms. ...
This study aims to create a quantitative polymerase chain reaction (q-PCR) methodology for monitoring the hydrogen-producing mixed cultures enriched from elephant dung using alpha-cellulose as a carbon source through five generations of repetitive sub-culture. The enriched thermophilic mixed cultures from...
In the second step (acidogenesis), along with CO2, hydrogen and alcohols, further degradation of monomers into short chain acids takes place. In the third step (acetogenesis), short chain acids are converted into acetate, CO2 and hydrogen. In the last step (methanogenesis), intermediates are ...
[99] demonstrated from water hyacinth that the fermentative production of hydrogen and ethanol is a feasible and sustainable process. Production of ethanol and hydrogen was significantly affected by iron nanoparticles. Fermentative hydrogen production and ethanol production were enhanced by iron nano-...
