Effect of Fermentation Ph on the Structure, Rheological Properties, and Antioxidant Activities of Exopolysaccharides Produced by Alteromonas Australica QD.

The pH value was essential for the growth and metabolism of microorganisms. Acidic pH exopolysaccharide (AC-EPS) and alkaline pH exopolysaccharide (AL-EPS) secreted by A. australica QD mediated by pH were studied in this paper. The total carbohydrate content and molecular weight of AC-EPS (79.59
