U(IV)-ion oxidation was monitored manometrically in cell suspensions ofThiobacillus ferrooxidans. The bacteria accelerated the oxygen uptake associated with U(4+)-oxidation, possibly resulting from cyclic regeneration of residual amounts of ferric io

A study was made of the effects of temperature and different microorganisms, or mixtures of microorganisms, on the changes in the nitrogenous constituents of mixed forest litters (mixed pine, oak, maple) during decomposition periods of up to 4 yr at

After 8 mo of decomposition, under laboratory conditions, the unlimed surface sample (0–15 cm, pH 3.8) of an acid peat bog contained about five times as many microbes as the unlimed subsurface material (15–41 cm, pH 4.1). As measured by CO2-C rel

The possible use of particle size separation of soils in water was tested for preparing fractions rich in ‘unknown’-N, which constitutes between 41 and 46% of the total N. Ten particle size fractions ranging from 1,000.0 μm were separated from t

Solutions of ferrous sulfate (pH 3.0) containing Mg- Al-, NH4- and alkali-saturated montmorillonite were inoculated with the iron-oxidizing bacterium Thiobacillus ferrooxidans and incubated for 451 days. In presence of K, NH4, Na and Li-montmorilloni
