NITRIFICATION OF SALINE EFFLUENTS

Simultaneous Elimination of Carbon and Nitrogen Compounds of Petrochemical Effluents by Nitrification and Denitrification

Bioremediation of saline effluents using Quinoa as a proposed solution to the crisis of shortage of drinking water resources

Background & Aim: The demand for freshwater resources has led scientists to use saline water and effluents. One of the cost-effective methods is the use of salinity-resistant plants to bioremediate saline effluents. Quinoa is a medicinal plant with high nutritional value that can control salinity stress in various ways. The present study was conducted with the aim of examining bioremediation of...

Urethanes and Soil Nitrification

Urethanes have marked physiological activity in plants and animals. Lefevre (1939) found that phenyl urethane affects wheat germination, and subsequently Templeman and Sexton (1946) showed that a variety of urethanes suppress the germination of wheat and oats without affecting charlock. The most active urethanes (for example, isopropylphenylcarbamate;ethylphenylcarbamate) are effective at a con...

Nitrification by Aspergillus flavus.

Marshall, K. C. (Cornell University, Ithaca, N. Y.) and M. Alexander. Nitrification by Aspergillus flavus. J. Bacteriol. 83:572-578. 1962.-Aspergillus flavus has been shown to produce bound hydroxylamine, nitrite, and nitrate when grown in peptone, amino acid, or buffered ammonium media. Free hydroxylamine was not detected in these cultures, but it was found in an unbuffered ammonium medium in ...

Plant influence on nitrification.

Modern agriculture has promoted the development of high-nitrification systems that are susceptible to major losses of nitrogen through leaching of nitrate and gaseous emissions of nitrogen oxide (NO and N2O), contributing to global warming and depletion of the ozone layer. Leakage of nitrogen from agricultural systems forces increased use of nitrogen fertilizers and causes water pollution and e...
