dity increases the need to chlorinate drinking water, which, in -products that have been shown to increase the risk of cancer. The ry agencies based on issues of and aerated/unaerated mass fractions are identified reasingly being seen as tand the relevant factors which differentiate competing to recover nutrients as process, sewage treatment plant Phosphorus: Total phosphorus (TP) in domestic w...

We evaluated the effect of phosphorus application rates from various sources and in the presence or absence of filter cake on soil phosphorus, plant phosphorus, changes in acid phosphatase activity, and sugarcane productivity grown in Eutrophic Red Ultisol. Three P sources were used (triple superphosphate, Araxa rock phosphate, and Bayovar rock phosphate) and four application rates (0, 90, 180,...

The phosphorus turnover of tumors has been widely studied in animals and has been found to be higher than in normal tissues. Several blood dyscrasias have also been investigated extensively (1-3). The high uptake of radiophosphorus by leukemic cells and by red cells in polycythemia vera has been applied to the treatment of these diseases (4, 5). Low-Beer and collaborators have observed an incre...

in order to evaluate the effect of increasing soil soluble phosphorus (p) and its effect on nitrogen (n) and p uptake, p uptake efficiency and p harvest index of black seed (nigella sativa l.) in a calcareous soil; a field experiment was conducted as factorial layout based on a randomized complete block design with three replications at research station, faculty of agriculture, ferdowsi univers...

Water shortage is one of the most important environmental stresses in Mediterranean regions. Poor seedling quality may account for the failure of oak regeneration. To determine the best seed origin of Quercus brantii, we investigated on seedlings collected from 20 mother trees in the Zagros Mountain forests 700 to 2200 m altitudes above sea level. Seedlings from different altitudes were irrig...

1. Four of the known components of wall preparations of vegative cells of Bacillus licheniformis N.C.T.C. 6346 have been isolated free of each other after successive treatments of the walls with trichloroacetic acid and lysozyme: (a) a mucopeptide consisting of glucosamine, muramic acid, alphain-diaminopimelic acid, glutamic acid and alanine in the molar proportions 1.0:0.8:1.0:1.2:1.7; (b) an ...

Phosphorus (P) is one of the major essential macronutrient for plant growth. Phosphate solubilizing bacteria (PCB) is a group of heterotrophic bacteria capable of solubilizing organic and inorganic phosphorus from insoluble compounds, releasing phosphate available for plant uptake. In this study endophytic bacteria were isolated form nodules of French bean grown in different intercropping syste...

Phosphorus solubilizing microorganisms are capable of transforming insoluble phosphorus (P) forms to soluble and bioavailable P. The aim of the present study was to isolate P solubilizing bacteria from forest soils around the rock phosphate (RP) mine of Koh-e-SepidLar in Kohgiluyeh and Boyer Ahmad province and evaluate their ability in Sperber culture medium and wheat straw medium in the presen...

The utilization of rocks as fertilizers is limited by their low solubility. However, solubilization may be achieved by some micro-organisms, such as ectomycorrhizal fungi (ECMf). The aim of this study was to evaluate the potential of seven isolates of ECMf to solubilize two rocks, alkaline breccia and granite, and to liberate potassium and phosphorus for Eucalyptus dunnii seedlings under greenh...

Chlorophyll-a and nutrient concentrations were monitored at weekly intervals across 21 river sites throughout the River Thames basin, southern England, between 2009 and 2011. Despite a 90% decrease in soluble reactive phosphorus (SRP) concentration of the lower River Thames since the 1990s, very large phytoplankton blooms still occur. Chlorophyll concentrations were highest in the mid and lower...
