Animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. Nitrogen has been identified as the foremost source of nonpoint water pollution  and the potential negative impacts of N have become an area of public concern. protein degradation from feed ingredients is an important factorinfluencing AA supply to the duodenum. Ruminal proteolysis...

the recently published articles in the iranian journal ofbiotechnology inspired us to write this short communication on nitrogen dioxide no2-philic plants (1).to cope with environmental pollution, we thought(still think) that development of methods that mitigatepollution is an urgent issue, and that no2-philic plantsthat can grow with no2 as the sole nitrogen source areinstrumental for the impl...

An experiment was conducted to study wheat grain protein increasing through foliar application of Nitrogen afterflowering. The RCBD design was analysed with three replications and four N-treatments as foliar application as(N0=0, N1=4kg.ha-1 Urea, N2=8kg.ha-1 Urea, N3=4kg.ha-1 Ammonium Sulfate). Results showed that seed proteincontent increased significantly by foliar application of Nitrogen. Da...

introduction ensiling is less dependent to weather condition and farmers are trying to ensile forages for preserving them for livestock feeding. ensiling legumes because of their buffering capacity and high moisture content are difficult. also, ensiling alfalfa will lose up to %85 of its nitrogen content as non-protein nitrogen. adding some additives like carbohydrate sources will improve alfal...

The Effect of Replacement Slow Releasing Non-Protein Nitrogen Source by Urea in Diets Containing Almond Hulls on Microbial Protein Production and Balance Sheep

in this study 152 bacterial strains were isolated from the contaminated oils in the southwest of iran. hemolysis was used as a criterion for the primary  isolation of biosurfactant producing-bacteria. fifty five strains had haemolytic activity , among them tweleve strains were good biosurfactant producers by measuring surface tension and emulsification activity.two microorganism showed the high...
