The effects of two dietary proteins on α-amino acids, calcium and phosphorus concentrations in plasma, stomach and intestine were investigated in rats trained to consume, in a single two-hour daily meal, diets containing α-lactalbumin (α-la) or whey protein concentrate (WPC) for two weeks. The results indicated that the concentrations of calcium and phosphorus in the gastrointestinal tract and ...

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...

As a beneficial endophytic fungus, arbuscular mycorrhizal fungi (AMF) are widely distributed in nature and can symbiotically grow with approx. 80% of terrestrial plants, helping host plants to develop increased tolerance various stresses. One the most important functions AMF is promote uptake P from soil by plant. The available findings explain role fungi. For example, increase phosphorus area ...

In the course of studies on the acid-soluble phosphorus compounds of liver and kidney, it became evident that the fraction comprising the nucleotides represented a complex mixture (1). In an attempt to isolate the individual nucleotides, methods designed to minimize the breakdown of labile phosphorus compounds were employed. The isolation of adenylic acid and of a material representing a mixtur...

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 ...

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...

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...

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 ...
