Obligately Thermophilic Nitrogen-Fixation in Some Soil Bacteria

Obligately Thermophilic Nitrogen-Fixation in Some Soil Bacteria

Date: August 1971
Creator: Milam, Mary
Description: In the work presented here, it is claimed that bacteria have been isolated which are capable of growth at high temperatures utilizing molecular nitrogen as their sole nitrogen source. Soil bacteria were isolated which grew at 55 C in nitrogen-free media. They were found to be obligatory thermophiles in nitrogen-free media and facultative thermophiles in media containing organically bound nitrogen.

Kinetic Investigation of the Gas Phase Atomic Sulfur and Nitrogen Dioxide Reaction

Kinetic Investigation of the Gas Phase Atomic Sulfur and Nitrogen Dioxide Reaction

Date: May 2011
Creator: Thompson, Kristopher Michael
Description: The kinetics of the reaction of atomic sulfur and nitrogen dioxide have been investigated over the temperature range 298 to 650 K and pressures from 14 - 405 mbar using the laser flash photolysis - resonance fluorescence technique. The overall bimolecular rate expression k (T) = (1.88 ± 0.49) x10-11 exp-(4.14 ± 0.10 kJ mol-1)/RT cm3 molecule-1 s-1 is derived. Ab initio calculations were performed at the CCSD(T)/CBS level of theory and a potential energy surface has been derived. RRKM theory calculations were performed on the system. It is found that an initially formed SNO2 is vibrationally excited and the rate of collisional stabilization is slower than the rate of dissociation to SO + NO products by a factor of 100 - 1000, under the experimental conditions.

Integrated Assessment of Hypoxia in the Northern Gulf of Mexico

Integrated Assessment of Hypoxia in the Northern Gulf of Mexico

Date: May 2000
Creator: National Science and Technology Council (U.S.). Committee on Environment and Natural Resources.
Description: This document details the ecological and economic effects of low oxygen (hypoxic) conditions in the Gulf of Mexico. This condition is caused by deforestation, river channelization, and the overuse of nitrogen in agricultural fertilizer. This document summarizes scientific evidence for the causes of hypoxia, the negative impact on Gulf of Mexico fisheries, and long-term national strategies for managing and mitigating the problem.

An Assessment of Coastal Hypoxia and Eutrophication in U.S. Waters

An Assessment of Coastal Hypoxia and Eutrophication in U.S. Waters

Date: November 2003
Creator: National Science and Technology Council (U.S.). Air Quality Research Subcommittee.
Description: This document is about hypoxia in aquatic ecosystems. Hypoxia is a depletion of oxygen caused by runoff, land cover change, and other factors associated with population growth and agriculture. The report discusses mitigation strategies and trends in managing this problem.
