Strain UHM-5, a pSym Exo derivative of the aluminum-tolerant Rhizobium leguminosarum bv. phaseoli strain CIAT899, was equally tolerant of aluminum (Al) as the parental culture. Dialyzed culture supernatants of the wild-type cells grown in YEM broth (10 cells ml) contained 185 mug of glucose equivalents ml whereas UHM-5 culture supernatants yielded 2 mug of glucose ml. The Exo derivative and the...

Arterial calcification (AC) is a common complication of end-stage renal disease (ESRD). The mechanisms responsible are complex, including disturbances of mineral metabolism and active expression of various mineral-regulating proteins. An inverse relationship between AC and bone density has been documented in uremic patients. In the study presented here, which included 58 patients with ESRD on h...

A self-powered electrocoagulation system with a single-chamber aluminum–air fuel cell was employed for phosphate removal in this study. Electricity production and aluminum hydroxides solution were also investigated. When the NaCl concentration increased from 2 mmol/L to 10 mmol/L, 86.9% 97.8% 60 min. An electrolyte composed of shown obtain maximum power density generation 265.7 mW/m2. initial p...

Cardiovascular mortality is the leading cause of death in the uremic patient. Hyperphosphatemia is considered an independent risk factor associated with cardiovascular morbidity and mortality in dialysis patients. As phosphate control is not efficient with diet or dialysis, phosphate binders are commonly prescribed in patients with chronic renal failure. Aluminum salts, the first phosphate bind...

We explored how phosphorus (P) availability influences accumulation of rare earth elements (REE) in plant species with different P-acquisition strategies beyond the commonly REE-phosphate precipitation. Two P-efficient carboxylate-releasing lupin (Lupinus albus, and L. cosentinii) four less carboxylate release under P-deficiency (Triticum aestivum, Brassica napus, Pisum sativum, Cicer arietinum...

A positive correlation has been demonstrated between the ability of Rhizobium strains to colonize acidic agar surfaces and their production of extracellular polysaccharide (EPS) in solution culture at pH 7.0. This set of experiments examined the effects of EPS on solution pH levels and Al activity, two common growth-limiting factors in acid soils. Samples of EPS from each of 20 previously acids...

the cold roll bonding of al on aisi 304l stainless steel was carried out to fabricate the al/304l/al clad sheet composites. the maximum bond strength of 20 n/mm was acquired just by 38% reduction, for which the tearing of the aluminum sheet occurred during the peeling test. the microstructural evolution during subsequent postannealing heat treatment was systematically studied based on the impur...

Aim: To study the effect of Rock Phosphate, Phosphorus Solubilizing Bacteria, and Lime on phosphorus content in soil, Uptake, Economic yield green gram (var. DGGS-4).
 Study Design: This experiment was conducted through a completely randomized design with 10 treatments 3 replications.
 Place Duration Study: The research at Department Soil Science Agricultural Chemistry, Central Univer...

preventing increases in calcium-phosphate product, secondary hyperparathyroidism and ultimately VC. CKD patients develop extensive medial calcification, which contributes to higher cardiovascular morbidity and mortality [2] . In addition to elderly age, male gender, inflammation, mineral metabolism abnormalities and diabetes, new potential factors are emerging which help to better understand th...
