Yeast assimilable nitrogen in South Moravian grape musts and its effect on acetic acid production during fermentation
stuck fermentation sluggish fermentation Vitis vinifela L. must yeast
2014/2/25
We observed the content of yeast assimilable nitrogen in grape musts, its consumption by yeasts during fermentation, and acetic acid production. The experiments were performed in the years 2007 and 20...
The Effect of Amino Nitrogen on the Energetics of Ruminal Bacteria and Its Impact on Energy Spilling
ruminal bacteria peptides amino acids energy
2008/7/24
The predominant ruminal bacteria that were obtained from a 108 dilution of ruminal fluid could be maintained as a mixed population for long periods as long as the bacteria were provided with a complex...
Use of Nitrogen from Ammoniated Alfalfa Hay, Urea, Soybean Meal, and Animal Protein Meal by Lactating Cows
ammoniation alfalfa ruminally degradable protein
2008/6/24
Midbloom alfalfa hay was baled (16% moisture) and treated with approximately 2% anhydrous NH3 (percentage of DM). Concentrations (percentage of DM) of total N (4.7% vs. 3.4%), NPN (1.3% vs. 0.4%), sol...

The rate of intake of peptides and free amino acids by Rahnella aquatilis was studied, as well as the evolution of concentrations of exopolysaccharide, biomass, and several metabolites. For this purpo...
Proteinase Activity of Pseudomonas fluorescens Grown in Cold Milk Supplemented with Nitrogen and Carbon Sources
extracellular proteinase production Pseudomonas intracellular adenosine triphosphate milk supplementation
2008/3/22
Extracellular proteinase activity varied when Pseudomonas fluorescens was grown at 7°C in UHT milk supplemented with different substrates. Addition of glutamine (5 mM) and glutamic acid (10 mM) reduce...
