The transformation of intermediate products of nitrification in soil


, : The transformation of intermediate products of nitrification in soil. Izvestiya Timiryazevskoi Sel' skokhozyaistvennoi Akademii (5): 83-88

In a laboratory experiment, hydroxylamine and NaNO2 labelled with 15N were incubated for 1-7 days under various conditions of aeration in a virgin derno-podzolic soil (pH 4.0) and an old ploughed soil (pH 6.3) with and without preliminary sterilization of the soil by autoclaving. In sterilized soil of pH 6.3, 43% of the hydroxylamine was fixed in organic form in the first 24 hours of incubation and 16% was lost as gaseous N2O.

The ability of hard ticks to prevent infection by bacteria was investigated. During a 72-h period, virtually all Dermacentor variabilis females survived inoculation with Bacillus subtilis, Escherichia coli, and Staphyloccocus aureus but few surviv...

Tyrosine phosphorylation of the cell cycle regulator p27(Kip1) plays a crucial role in its binding to cyclin dependent kinases and its subcellular localization. While Src and Bcr-Abl were shown to be responsible for tyrosine phosphorylation, no da...
