nitrate pollutants increase the growth of algal bloom, resulting in fresh water eutrophication. the high nitrogen level in wastewater has become a growing concern, which has risen the necessity to develop efficient nitrogen removal techniques. biological denitrification, which is the reduction of oxidized nitrogen compounds like nitrate or nitrite to gaseous nitrogen compounds, is the most impo...

The class of compounds called non-protein nitrogen (NPN) is not a homogeneous group of similar chemicals but rather an operational term for the remainder of nitrogen in milk and formula once the protein fraction has been removed. NPN therefore consists of widely diverse types of compounds, ranging from urea to complex nitrogen-containing oligosaccharides. It is obvious that the capacity of an i...

Pittman, K. A. (Agricultural Research Service, Beltsville, Md.), and M. P. Bryant. Peptides and other nitrogen sources for growth of Bacteroides ruminicola. J. Bacteriol. 88:401-410. 1964.-Representative strains of Bacteroides ruminicola were found to utilize peptide nitrogen or ammonia nitrogen, but not to utilize significant amounts of free amino acid nitrogen or the nitrogen from a variety o...
