batch culture of ralstonia eutropha using the recycled gas closed circuit culture system was conducted in order to develop a practical fermentation system for industrial autotrophic culture for poly (hydroxybutrate) production. the gas phase of the culture system consisted of substrate gas so that gases in this culture could be recycled as long as the amount of the gas consumed would be repleni...

An investigationi was undertaken to determine the oxygen absorption rates of a submerged culture of Bacillus anthracis at all stages of its growth cycle. The determination of oxygen absorption rates of a pathogenic fermentation such as this by analysis of the exhaust gases seemed to present fewer technical difficulties than did those methods that depended upon polarographic determination of dis...

Polymer electrolyte membrane (PEM) fuel cells are highly efficient energy converters and provide electrical energy, cathode exhaust gas with low oxygen content, water and heat. Recently, fuel cells have been investigated for the use on aircraft where they have the potential of replacing the auxiliary power units (APU) that are currently used for generating electrical power during ground operati...

When looking at the effects of diesel engine exhaust on the environment, it is important to first look at the composition of the exhaust gases. Over 99.5% of the exhaust gases are a  combination of  nitrogen, oxygen, carbon dioxide, and water. With the exception of carbon  dioxide, which contributes about  5% of the total volume, the diesel engine exhaust consists of  elements which are part of...

The exhaust gases of gas turbine power plant carry a significant amount of thermal energy that is usually expelled to the atmosphere this causes a reduction in net work and efficiency of gas turbine. On the other hand, the generated power and efficiency of gas turbine plants depend largely on the temperature of the inlet air, So that they both increase as the inlet air temperature decreases. Th...

Polymer electrolyte membrane fuel cells are efficient energy converters and provide electrical energy, water and oxygen depleted air with a low oxygen content as exhaust gas if fed with air. Due to their low emission of greenhouse gases and noise they are investigated as replacement for auxiliary power units currently used for electrical power supply on aircraft. Oxygen depleted air, called ODA...
