Waterfowl Impoundments as Sources of Nitrogen Pollution

s-Triazines as Nitrogen Sources for Bacteria

Isolation of bacteria able to utilize s-triazines as the sole and limiting nitrogen sources for growth is described. Three strains of Pseudomonas (A, D, and F) and two strains of Klebsiella pneumoniae (90 and 99) were examined. Strains D and F utilized N-ethylammelide, N-isopropylammelide, ammeline, ammelide, cyanuric acid, and ammonium ion as nitrogen sources. Strain A utilized melamine, ammel...

Biological and organoleptic properties of milk protein as affected by dilution with non-esential nitrogen sources

Point Sources of Pollution

Evaluation of foods as sources of nitrogen and amino acids.

In any managed system of animal production the problem is to match the nutrient requirement of the animal with a supply of the nutrient in the feed to achieve the maximum economic return. Any matching system has one major prerequisite : the nutrient requirement and nutrient content of feedstuffs must be expressed in the same units. The manner in which this matching is carried out may differ acc...

Anthropogenic air pollution sources

What one experiences today as atmosphere is a transient snapshot and result of its evolutionary history. Much of the development and present status was explained based both on scientific knowledge, and combined with established facts, even speculation. The planet Earth was formed around 4600 million years ago by the gravitational accretion of relatively small rocks and dust, within the solar ne...
