The anion such as calcium (Ca2+), magnesium (Mg2+) iron (Fe2+), sodium (Na+), potassium (K+) and cations such as, carbonate (CO32−), bicarbonate (HCO3−), chloride (Cl−), sulfate (SO42−) and nitrate (NO3−) are the essential sources of salinity; nevertheless, sodium ...
Growth of the WT and mutants was measured on glycans by mixing the autoclave-sterilised polysaccharides (0.5% final) with minimal media (per 100 ml was: 0.1 g of Ammonium sulfate and sodium carbonate, 0.05 g cysteine, 10 ml 1 M potassium phosphate pH 7.2, 0.1 ml of 1...
An initial concentration of 99% ACN with 5% ddH2O (buffer B) and 5% 25 mM ammonium carbonate in ddH2O (buffer B) was held for 1 min at a flow rate of 0.2. B was decreased to 10% over 14 min and held for 5 min. B was returned to starting conditions over 0.1 min, and the ...
The carbonate ion (CO2−3) can undergo hydrolysis in water. Hydrolysis is a reaction with water that leads to the formation of a weak acid and a strong base. The carbonate ion reacts with water to produce bicarbonate (HCO−3) and hydroxide ions (OH−):...
