High-level production of calcium malate from glucose by Penicillium sclerotiorum K302.
In this study, after screening of 9 fungal strains for their ability to produce calcium malate, it was found that Penicillium sclerotiorum K302 among them could produce high-level of calcium malate. Under the optimal conditions, the titer of calcium malate in the supernatant was 88.6 g/l at flask level. During 10-l fermentation, the titer of…

Calcium lactate as an attractive compound to partly replace salt in blue-veined cheese.
In addition to their high sodium content, cheeses are thought to induce an acid load to the body, which is associated with deleterious effects on consumers’ health. Our objective was to explore the use of alkalinizing salts in partial substitution of NaCl to reduce both the sodium content and the acid-forming potential of cheese, without…

Anti-inflammatory effects of calcium citrate in RAW 264.7cells via suppression of NF-κB activation.
Here we aimed to investigate the anti-inflammatory effects of calcium citrate in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The anti-inflammatory effects of calcium citrate were investigated by assessing pro-inflammatory factors (NO, ROS, NF-κB, iNOS, and COX-2) and pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α). Treatment of cells with calcium citrate (10-100μM) significantly reduced the generation of intracellular…

Preparation and properties of calcium citrate nanosheets for bone graft substitute.
A convenient and effective soft chemical method is presented for the synthesis of nano-scaled calcium citrate sheets. The preparation involved the precipitation of nano-calcium citrate by adding ethanol to reach the super saturation state of a solution containing calcium and citrate salts. The obtained nano-calcium citrate formed nanosheets, with the following dimensions: width of about…

Codissolution of calcium hydrogenphosphate and sodium hydrogencitrate in water. Spontaneous supersaturation of calcium citrate increasing calcium bioavailability.
The sparingly soluble calcium hydrogenphosphate dihydrate, co-dissolving in water during dissolution of freely soluble sodium hydrogencitrate sesquihydrate as caused by proton transfer from hydrogencitrate to hydrogenphosphate, was found to form homogenous solutions supersaturated by a factor up to 8 in calcium citrate tetrahydrate. A critical hydrogencitrate concentration for formation of homogeneous solutions was found to…

Supersaturation of calcium citrate as a mechanism behind enhanced availability of calcium phosphates by presence of citrate.
Dissolution of amorphous calcium phosphate (ACP) in aqueous citrate at varying pH has been studied with perspective of increasing availability of calcium from sidestreams of whey protein, lactose and/or cheese production or on development of new functional foods. ACP formed as an initial precipitate in 0.10 mol L-1 equimolar aqueous calcium chloride, sodium citrate, and sodium hydrogenphosphate…

Chronic Ingestion of Sodium and Potassium Bicarbonate, with Potassium, Magnesium and Calcium Citrate Improves Anaerobic Performance in Elite Soccer Players.
Anaerobic power and anaerobic capacity significantly influence performance in many sport disciplines. These include prolonged sprints in athletics, swimming, or cycling, and other high intensity intermittent sports, such as soccer or basketball. Considering the association of exercise-induced acidosis and fatigue, the ingestion of potential buffering agents such as sodium bicarbonate, has been suggested to attenuate…

Calcium citrate insolubilization drives the fouling of falling film evaporators during the concentration of hydrochloric acid whey.
When dairy powders are produced, the mineral fraction undergoes strong modifications during the vacuum concentration step, leading to the fouling of falling film evaporators. The objective of this study was to determine the nature of the deposits formed during the vacuum concentration of two fouling and highly mineralized products: hydrochloric acid whey and lactic acid…

Mechanism by which ammonium bicarbonate and ammonium sulfate inhibit mycotoxigenic fungi.
In this study we examined the mechanism by which ammonium bicarbonate inhibits mycotoxigenic fungi. Elevated extracellular pH, alone, was not responsible for the antifungal activity. Although conidia of Penicillium griseofulvum and Fusarium graminearum had internal pH (pHi) values as high as 8.0 in buffer at an external pH (pHo) of 9.5, their viability was not…
