The dye reagent is buffered by M/10 phosphate salts at pH 7.4 and is prepared by dissolving 12.07 gm. anhydrous disodium hydrogen phosphate powder, 2.04 gm. potassium dihydrogen phosphate crystals, 2.60 gm. sodium arsenite powder, and 2.10 gm. sodium fluoride powder in 1 L. of distilled water. Sufficient 2,6-dichlorobenzenoneindophenol sodium is added to bring the absorbance of the solution to ...

Geoactive soil fungi were investigated for phosphatase-mediated uranium precipitation during growth on an organic phosphorus source. Aspergillus niger and Paecilomyces javanicus were grown on modified Czapek-Dox medium amended with glycerol 2-phosphate (G2P) as sole P source and uranium nitrate. Both organisms showed reduced growth on uranium-containing media but were able to extensively precip...

The following studies were initially undertaken to investigate the quantitative relations of potassium changes in blood and muscle after adrenalectomy in the light of the work done on the nature of potassium accumulation (Boyle & Conway, 1941). In the course of the investigation the mean values of the known and quantitatively important substances in muscle and plasma were determined. These incl...

Results of studying the domain structure planar Ni microparticles formed on single-crystal substrates from lithium niobate and potassium titanyl phosphate at different temperatures are presented. The dependence sizes sample temperature was studied. It is shown observed change caused by magnetoelastic effect, which arises due to difference in thermal expansion coefficients substrate as changes. ...

Background: Erythromycin production often has concern with the consumption rate of amino nitrogen and phosphate, especially in the early fermentation phase. The dynamic regulation of nitrogen and phosphorus was put forward based on the comprehensive analysis of the contents of phosphorus and nitrogen in different nitrogen sources as well as the relations between nitrogen consumption and phospho...

INTRODUCTION The contamination of serum or lithium heparin blood with ethylenediaminetetraacetic acid (EDTA) salts may affect accuracy of some critical analytes and jeopardize patient safety. The aim of this study was to evaluate the effect of lithium heparin sample contamination with different amounts of K2EDTA. MATERIALS AND METHODS Fifteen volunteers were enrolled among the laboratory staf...

Chemical fertilizer use in agricultural areas causes a variety of issues, including pollution, health risks, disruption natural ecological nutrient cycles, and the loss biological communities. In this case, chemical fertilizers, herbicides, other supplements are replaced by plant growth promoting bacteria for sustainable agriculture. The present research work focus on isolation from Kadi vegeta...
