This paper presents data on the distribution of acid-soluble phosphorus compounds in the blood cells of a few apparently normal individuals of each of forty-six species: twenty-two mammalian, twelve avian, six reptilian, four amphibian, and two fish. Since the studies were limited by availability of material, each order is represented by only a few species, and in many instances only one blood ...
Equilibrium-tension lysimeters were used to evaluate and compare dissolved reactive phosphorus (DRP) leaching from a prairie and fertilized no-tillage and chisel-plowed corn agroecosystems on Plano silt loam (fine-silty, mixed, superactive, mesic Typic Argiudolls) in south central Wisconsin during four monitoring periods, March through April 1996, 1997, and 1998, and from January 1999 through S...
1. The experimental barley samples included 4 hulled and one hull-less low-phytate barley cultivars and two commercial barley varieties as controls. 2. The diets were provided in meal form, with the experimental barley samples constituting the cereal source. Two additional treatments were added for each of the control varieties in which intermediate and recommended levels of phosphorus were pro...
[1] The global tropospheric budget of gaseous and particulate non-methane organic matter (OM) is re-examined to provide a holistic view of the role that OM plays in transporting the essential nutrients nitrogen and phosphorus to the ocean. A global 3-dimensional chemistry-transport model was used to construct the first global picture of atmospheric transport and deposition of the organic nitrog...
Microalgae in waste stabilization ponds (WSP) have been shown to accumulate polyphosphate. This luxury uptake of phosphorus is influenced by the wastewater phosphate concentration, light intensity and temperature, but the dynamics of how these factors affect luxury uptake with respect to time are not understood. With improved understanding of the dynamics of this mechanism and how it could be m...
This study examined the utilization of potato processing wastewater as the feedstock by two oleaginous fungi, Aspergillus flavus I16-3 and Mucor rouxii, for lipid and gamma linolenic acid production. The high strength wastewater contained soluble carbohydrates of 36.2 g/l, soluble chemical oxygen demand (COD) of 40 g/l, total soluble nitrogen of 0.62 g/l, and soluble total phosphorus of 0.24 g/...
In this work, the effect of raw and modified bentonite and zeolite with trivalent iron on the stabilization of water-soluble and adsorbed arsenic in a calcareous soil was studied. Raw and modified bentonite and zeolite were added to the soil in different weights in a completely randomized block design with three replications and kept to field capacity soil moisture content of 80% for 8 weeks. T...
Non-collagenous, soluble proteins and collagen have been extracted quantitatively from freshly dissected chicken bone at 4 ûC in presence of protease inhibitors, and their content in organic phosphorus assayed. We found that non-collagenous proteins were not covalently bound to collagen in chicken bone, as in some calcified tissues. They represented 30 p. 100 of the organic matrix and bound 75 ...
