The objective of the research reported here was to determine amount nitrogen fixed from atmosphere and taken up mineral fertilizer soil reserves by soybean cv. Abelina grown at three densities (per 1 m2) under central European conditions. Moreover, an attempt made what individual sources removed field with seed yield introduced post-harvest residues that will be source this macronutrient for fo...

Symbiotic nitrogen fi xation has important role in sustainable soybean production because of utilization of atmospheric nitrogen for soybean nutrition. Pre-sowing soybean seed inoculation with selected rhizobial strains is used to improve the amount of symbiotically fi xed nitrogen. Besides strain selection, suitable inoculant formulation is important for the success of inoculant application. T...

The root nodule symbiosis (RNS) between legume plants and rhizobia is the most efficient and productive source of nitrogen fixation, and has critical importance in agriculture and mesology. Soybean (Glycine max), one of the most important legume crops in the world, establishes a nitrogen-fixing symbiosis with different types of rhizobia, and the efficiency of symbiotic nitrogen fixation in soyb...

The production of thermostable extracellular protease by Bacillus stearothermophilus F1 was influenced by the composition of culture medium. Peptone iv derived from soybean was the best organic compound for enzyme production. Sodium nitrate, ammonium salts and amino acids as sole nitrogen sources interfered with protease formation. The addition of most carbon sources to the peptone medium faile...

Lipase produced by Aspergillus niger is widely used in various industries. In this study, extracellular lipase production from an industrial producing strain of A. niger was improved by medium optimization. The secondary carbon source, nitrogen source, and lipid were found to be the three most influential factors for lipase production by single-factor experiments. According to the statistical a...

Protein content of any source is classically determined through the analysis of its nitrogen content done for more 100 years by the Kjeldahl method, and the obtained result is multiplied by a number named nitrogen conversion factor (NCF). The value of NCF is related to the amino acid composition of the protein source and to the eventual presence of side groups covalently bound to some amino aci...

The objective of this study was to determine the effects of supplementing dried distillers grains soybean hulls, or combinations of the two to growing beef steers consuming bahiagrass hay. Angus steers were randomly allotted to one of four supplement treatments. Treatments included: 1) dried distillers grains; 2) dried distillers grains/soybean hulls; 3) soybean hulls/distillers grains; 4) soyb...
