native phosphate solubilizing bacteria (psb) were isolated from four areas (ankober, keyt, mehalmeda and molale) of ethiopia to study their effect on releases of soluble phosphorus from insoluble p sources. the highest bacterial number was found at keyt (2.6103 g-1soil) and the least at molale (15 g-1soil). five efficient psb were selected for further study based on their ability in forming a ...

introduction: use of unbalanced chemical fertilizers especially p, having low absorption efficiency and low solubility compounds with soil components, has resulted in the production and use of bio-fertilizers (17, 23 and 29). bio-fertilizer is a preservative material consisting of one or several specific beneficial micro-organisms or their metabolic products used to supply plant nutrients and d...

Phosphorus removal in waste stabilization ponds (WSP) is highly variable, but the reasons for this are not well understood. Luxury uptake of phosphorus by microalgae has been studied in natural systems such as lakes but not under the conditions found in WSP. This work reports on the effects of phosphate concentration, light intensity, and temperature on luxury uptake of phosphorus by WSP microa...

The different combinations of phosphorus to be found in a given tissue may be divided into three main groups: I. Protein phosphorus or phosphorus in combination with protein, including nucleoprotein and phospho-proteins or nucleoalbumins, insoluble in water especially after treatment with alcohol; 2. Lecithin and kephalin phosphorus or phosphorus in combination with fat and a nitrogen complex, ...

1. The cell wall of Clostridium welchii (type A) contains alanine, 2,6-diaminopimelic acid, glutamic acid, glycine, glucosamine, muramic acid, galactosamine, mannosamine, ethanolamine, rhamnose, galactose and phosphorus. 2. Heating with formamide at 150 degrees resolved the wall into a formamide-soluble polysaccharide fraction and a formamide-insoluble mucopeptide fraction. 3. The formamide-sol...

When ‘25l-labeled blood platelets were lysed with an equal volume of 2% Triton X-100, 10 mM EGTA, and 100 mM Tris, pH 7.4. the Triton-insoluble residue (“cytoskeleton”) contained about 1 1 % of the platelet protein. predominantly actin and actin-binding protein, 3.5% of the platelet radioactivity, and less than 2% of the platelet lipid phosphorus. Radioautographs of polyacrylamide gels of this ...

Cotton, an important commercial crop, is cultivated for its natural fibers, and requires an adequate supply of soil nutrients, including phosphorus, for its growth. Soil phosporus exists primarily in insoluble forms. We isolated a mitochondrial malate dehydrogenase (MDH) gene, designated as GhmMDH1, from Gossypium hirsutum L. to assess its effect in enhancing P availability and absorption. An e...

Soils generally contain adequate amount of inorganic and organic phosphorous but most of these remain unavailable to plants. The efficiency of water soluble phosphorus alone is usually low and soluble phosphorus when added to soil along with phosphate solubilizing microorganisms indicates utilization. The presence of soil microorganisms capable of transforming insoluble phosphorus to soluble fo...
