A single, low-density (1.58 g/cm3), phosphatic coprolite recovered from a fluvial Triceratops site in the Upper Cretaceous Hell Creek Formation of eastern Montana contains small quantities of minute bone or tooth fragments, kerogenized plant residues

Coprolites were collected 74 m above the base of the Upper Triassic Ischigualasto Formation of northwestern Argentina and their chemistry, mineralogy, and textures were studied to infer their biological source and taphonomy. They were found to contai

The Cretaceous Two Medicine Formation of northwestern Montana has yielded blocky, calcareous coprolites that contain abundant fragments of conifer wood and were produced by large herbivorous dinosaurs. The coprolites are generally dark gray to black

The reductases of the denitrification pathway of Bacillus stearothermophilus, a thermophilic denitrifier, were surveyed in vitro. Nitrate, nitrite and nitric oxide reductases were found to be membrane-bound, and nitrite reductase may be a copper-cont

Nitric oxide reductase from Achromobacter cycloclastes was solubilized with dodecyl maltoside from membranes and substantially purified by hydroxyapatite column chromatography. Preparations of enzyme had purities estimated to be 65–72% and specific

Kinetic studies were carried out on the oxidation of dithionite-reduced, monoheme cytochromes c by nitrous oxide reductase from Wolinella succinogenes. These reduced cytochrome c-N2O oxidoreductase systems showed second-order kinetics, first-order ea

Samples of water, sediment and bacterial mat from hot springs in Graendalur and Hveragerdi areas in southwestern Iceland were screened at 70°C and 80°C for thermophilic denitrifying bacteria by culturing in anaerobic media containing nitrate or N2O

The subcellular distribution of nitrous oxide reductase was studied in the gliding soil bacterium Flexibacter canadensis. Nitrous oxide reductase activity, as measured by the methyl viologen-nitrous oxide oxidoreductase assay, was associated entirely

Nitric oxide reductase was purified from Paracoccus denitrificans very nearly to homogeneity by a simple method that involved the use of octyl glucoside to solubilize the enzyme from membranes and required a single hydroxyapatite column. The enzyme h

Two denitrifying bacteria, Pseudomonas stutzeri and Achromobacter cycloclastes, were incubated with Na15NO2 and NaN3 under conditions that allowed catalysis of nitrosyl transfer from nitrite to azide. This transfer, which is presumed to be mediated b
