Biochemical and Genetic Characterization of Reduced Phosphorus Metabolism in Pseudomonas Stutzeri WM88
… detailed biochemical and genetic analysis of reduced P metabolism in microorganisms is described in this thesis. Pseudomonas stutzeri WM88 is able to oxidize hypophosphite (P valence +1) and phosphite (P valence +3) for their use as the sole source of P. This process requires two operons …

Characterization of Reduced Phosphorus Metabolism in Alcaligenes Faecalis WM2072 and Xanthobacter Flavus WM2814
… herein describe the characterization of reduced phosphorus metabolism in two recently isolated bacteria. These bacteria were found by performing enrichments to isolate organisms that could utilize reduced phosphorus compounds as their sole phosphorus source. Two of these isolates that …

Nutritional evaluation of conventional, high protein, reduced fiber, and reduced phosphorus corn co-products for poultry
… protein (CFP), high protein-DDGS (HP-DDGS), reduced fiber high protein-DDGS (RFHP-DDGS), and reduced phosphorus-DDGS (RP-DDGS) were evaluated. The precision-fed rooster assay was utilized to measure TMEn and standardized amino acid (AA) digestibility. Corn fermented protein contained an …

Phosphorus in the Environment and its Role in Anaerobic Iron Corrosion
Phosphorus chemistry controls key aspects of eutrophication, microbial nutrition, corrosion and other environmental processes. It is commonly assumed that phosphorus occurs exclusively as phosphate (+5) in nature. In fact, although phosphate is undoubtedly dominant in many systems, phosphorus …

The effects of foliar applications of seaweed extracts on plant growth and pest resistance
… yield and quality, on tissue levels of nitrogen, phosphorus, and potassium, or on populations of potato leafhopper (PLH), Empoasca fabae (Harris). For the fourth cutting, fertilizer and kelp*fertilizer effects were observed. Yield and tissue levels of potassium were higher and PLH numbers were …

The Effects of Neuroendocrine Stress on Larval Development
… treated with GC hormones had lower nitrogen to phosphorus ratios, possibly because disrupted skeletal ossification. They also had reduced phosphorus excretion, which could affect ecosystem-level processes like nutrient cycling and decomposition.

SYNTHESIS, CHARACTERIZATION, AND THERMAL INVESTIGATION OF METAL PHOSPHITES AND POTENTIAL IMPLICATIONS FOR ASTROBIOLOGY
<p>The role of phosphorus in biochemistry is well understood. However, the route by which phosphorus was incorporated into early biomolecules on the prebiotic Earth is uncertain. Phosphate, the most prevalent species of phosphorus found in Earth’s geological record, is insoluble and unreactive with …

A Diverse Array of Synthetic Strategies for Phosphorus Group Transfer Chemistry: From Phosphinidenes to Phosphates
… of novel synthetic methods for the transfer of phosphorus-containing moieties, specifically metaphosphates and phosphinidenes. The work presented here has significant implications for both the fundamental understanding and practical advancement of synthetic inorganic and organic chemistry. …

Financial costs and economic tradeoffs of alternative manure management policies on dairy and dairy/poultry farms in Rockingham County, Virginia
… to agronomic recommendations (NLIMIT), and phosphorus applications limited to crop removals (PLIMIT), on representative 60, 100, and 150-cow dairy and dairy/poultry farms. Current nutrient applications are manure-based, with each farm substituting poultry litter for commercial fertilizer. …
