The cell surface of alkaliphiles has a high concentration of ,acidic, (i.e. negatively charged) molecules and it has been suggested this acts as a “proton sponge”, allowing a more rapid lateral diffusion of protons from the ETS, to the ATP synthase, compared to the rate of diffusion into the surrounding waters [1] Finally, alkaliphiles may use Na + /H + antiport to create a sodium motive force.

acidic, groups, at pH 2.5 carboxylate and sulfate groups are stained by Alcian Blue, while at pH 1.0 only sulfate groups are stained.23 For staining at pH 2.5, an adapted protocol of Møller and Poulsen (2009)24 was used. After ,electrophoresis,, the gels were extensively washed in solution I (25% (v/v)

US EPA offers another alternative method to measure FA. The oxime derivatives were formed by adding pentafluorobenzyl hydroxylamine (PFBHA) reagent to FA solution at pH of 4. Then they are extracted from the water with 4mL hexane. After processing through an ,acidic, wash step, the extracts are analyzed by GC with electron capture detection (GC/ECD).

Solutions with a higher [H+] than water (pH less than 7) are ,acidic,; solutions with a lower [H+] than water (pH greater than 7) are basic ,or alkaline,. Definition of pH Measuring pH involves comparing the potential of solutions with unknown [H+] to a known reference potential. pH meters convert the voltage ratio between a reference half-cell and a sensing half-cell to pH values.

to treat ,wastewater,. The purpose of the study was removing iron and sulfate from very saline synthetic ,waste-water, by means of halophilic sulfate-reducing bacteria. This process was performed under anaerobic conditions to change ,wastewater, to a chemical fertilizer to use in saline and ,alkaline, soils. Three halophilic SRBs were isolated

Biohydrogen Production from Wastewaters | IntechOpen

Biohydrogen production technology is an emerging field for the advanced ,wastewater, treatment with cogeneration of energy. Besides, hydrogen is an excellent candidate with high energy value (122 kJ/g) than other known carbon‐based fuels with no adverse effects to the environment as it releases only water vapor as the by‐products during the combustion.

ranges from 180 – 880 PtCo units. Other pollutants in the textile ,wastewater, include TSS, VSS and NH 3-N. In terms of acidity, the ,wastewater, was either very ,acidic, (pH 3.9) or very ,alkaline, (pH 11.4). With the high load of pollutants, efficient treatment is highly desirable before the ,wastewater, can be di scharged.

Ethylenediaminetetraacetic acid - Wikipedia
Ethylenediaminetetraacetic acid - Wikipedia

Ethylenediaminetetraacetic acid, (EDTA) is an aminopolycarboxylic acid with the formula [CH 2 N(CH 2 CO 2 H) 2] 2.This white, water-soluble solid is widely used to bind to iron and calcium ions. It binds these ions as a hexadentate ("six-toothed") chelating agent.EDTA is produced as several salts, notably disodium EDTA, sodium calcium edetate, and tetrasodium EDTA.
