In this study, the MgCl2/red mud system (MRM) was used to investigate the color removal efficiency of dye solutions. Parameters such as the effect of the dosage of red mud (RM) and MgCl2 have been studied. The effect of pH on the conversion rate of Mg2+ has also been studied. The color removal efficiency of MRM was compared with that of PAC/RM and PAC/NaOH. Meanwhile, the color removal efficien...

Tryptic digestion of the junctional sarcoplasmic reticulum membranes in sucrose but not NaCl buffer leads to complete loss of ryanodine binding capacity. The presence of MgCl2 in the sucrose buffer prevents the loss of ryanodine binding by the trypsin treatment. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the treated membranes reveal that the 400-kDa protein band disappeared un...

By use of poly(dA-dT) as template and Escherichia coli RNA polymerase, several metal ions were tested for their effect on the efficiency of transcription and on the misincorporation of CMP into the poly(rA-rU) product. In the presence of 10 mM MgCl2, Mn2+ has a stimulatory effect on the transcription, Co2+ has very little effect on the reaction, Cu2+ and Zn2+ are strongly inhibitory, and Cd2+ a...

OBJECTIVE This study was performed to determine effects of different curing salts on the quality of salamis and to assess feasibility of using NaCl-alternative salts. METHODS Various types of curing salts (KCl or MgCl2) as well as NaCl (sun-dried or refined) were incorporated for processing of salamis. The proximate composition, fatty acids, nucleotide-related compounds, and free amino acids ...

1. In respiring rat liver mitochondria EDTA stimulates glutaminase activity measured in the presence of phosphate and HCO3- ions. The stimulation can be reversed by the addition of low concentrations of MgCl2. EGTA does not stimulate glutamine hydrolysis. 2. Glutaminase activity assayed in disrupted mitochondria is not significantly affected by EDTA or MgCl2. 3. The addition of EDTA results in ...

Natural, H2O2 and MgCl2 modified Light Weight Expanded Clay Aggregate (LECA) were used as fluoride adsorbents. Characterization of LECA and its modified forms was done by infra-red, X-ray diffraction, scanning electron microscope and X-ray fluorescence studies. The specific surface area of HML and MGML was 3.34 and 3.97 times greater than that of NL (11.72 m/g). Improved chemical composition of...
