The content of the phosphorus fractions in bacillus spores reveal a marked difference in the quantity of residue phosphorus (Fitz-James and Young, 1959). In particular, the spores of two strains of Bacillus megaterium contained a residue phosphorus of over 1 per cent of the dry weight whereas in another strain it was essentially nil. This residue fraction remaining after a modified Schmidt and ...

plant growth promoting rhizobacteria and arbuscular mycorrhizal fungi can inhanced plant growth by increasing nutrient uptake. in order to investigate the effect of pgpr and amf on some morphological parameters, macro (nitrogen, phosphorus, potassium, calcium and magnesium) and micro (iron, zinc and copper) nutrients uptake, percentage of root colonization and some morphological factors of pepp...

The immobilization and mineralization processes carried out by soil microorganisms have a significant role in controlling the availability of phosphorus soil. A class helpful known as phosphate solubilizing microbes are able to hydrolyze insoluble organic inorganic compounds into soluble P (phosphorus) form that is readily taken plants. objective this study was evaluate different waste Aspergil...

Zinc electrowinning is performed with the application of a current through insoluble electrodes (Pb-Ag), causing the electrolysis of zinc sulfate, with or without impurities, and zinc deposition on the cathode of aluminum. The impurities can reduce the current efficiency and increase the energy consumption in zinc electrolysis. In this work, the effect of nickel and magnesium on zinc electrodep...

1. Fibrin clots obtained from diluted human plasma with bovine thrombin often contain amounts of phospholipids that cannot be diminished by further plasma dilution. 2. The ;cold insoluble residue' obtained during fibrinogen preparation has a higher phosphorus content than the purified fibrinogen. 3. Evidence showed that adsorption of phospholipids or phosphorus-containing fibrinopeptides on pur...

Semifluorinated alkanes, RFRH, have a perfluorocarbon and a hydrocarbon segment in the molecule. RFRH are physically, chemically and physiologically inert, colorless, laser stable liquids with substantially reduced densities - between 1.1 and 1.7 g/cm3 - and very low surface and interface tensions. RFRH are useful for unfolding a retina or for permanent tamponade. They are soluble in perfluoroc...

Based on the large number experiments on solubilization of poorly watersoluble drugs, the author is of the opinion that hydrotropy is another type of cosolvency and all water soluble substances whether solids, liquids or gases have solubilizing properties. Therefore, aqueous solutions containing small quantities of several water-soluble excipients giving a concentrated solution, may act as a so...

The use of polyethylene glycol 4000 as a non-absorbable, continuously fed faecal marker is described. The intestinal handling and transit of polyethylene glycol is compared with that of chromium sesquioxide and barium sulphate. Polyethylene glycol is an acceptable non-absorbable faecal marker for calcium, phosphorus, and fatty acids, and has several features which commend its use in preference ...
