5A). In medium without amino acid supplementation, pyruvate fermentation was required for the initiation of N2O consumption (Fig. 1C), raising the question if pH impacts pyruvate fermentation by the Serratia sp., N2O reduction by the Desulfosporosinus sp., or both processes. Axenic Serratia sp...
Therefore, at a urine pH of 5.3, half of the amount of the total urate in the urine will be in the form of uric acid, which is poorly soluble in water (solubility 0.6 mmol/L). A low urine pH is the most important risk factor for formation of uric acid stones. The medullary shunt...
2.2.1. Water pH effect The aqueous solutions of different pH were prepared by mixing adequate amounts of NH4OH in demineralized distilled water for basic solutions (pH: 8–13), whereas acidic medium (pH: 2–6) was prepared with HCl in water. The pH value for each solution was controlled...

pH is the negative log of hydrogen ion concentration in a water-based solution. The term "pH" was first described by Danish biochemist Søren Peter Lauritz Sørensen in 1909. pH is an abbreviation for "power of hydrogen" where "p" is short for the German word for power,potenzand H i...
