High-Efficiency Extraction of Pantoea alhagi Exopolysaccharides Driven by pH-Related Changes in the Envelope Structure.

ABSTRACT: Increasing numbers of exopolysaccharides and their properties have been explored. However, the difficulty of extracting high-viscosity exopolysaccharides has hindered their further industrialization. In this research, we explored a strategy based on encapsulated structure control under different pH to efficiently extract Pantoea alhagi exopolysaccharides (PAPS). Results showed that at pH levels of 6, 12, and 13, the extraction efficiency of PAPS was elevated, and the yield did not decrease. The rheological properties of the pH-12-treated PAPS were better than those of PAPS treated at pH 7, while the pH-6-treated PAPS decreased. The effects of pH-12-treated PAPS on soil macroaggregates and soil's water evaporation rate were similar to those of PAPS treated at pH 7. In addition, we ob
