Abstract
The invention is directed to a method of increasing the chemical and/or thermal stability of PHA in biomass where the biomass is contained within mixed liquor, and wherein the mixed liquor is treated by a combination of removing water from the mixed liquor and pH adjustment of the mixed liquor or maintenance of the pH of the mixed liquor within a selected pH range, and wherein the method includes reducing the pH of the mixed liquor below 6, or maintaining the pH of the mixed liquor below 6 for a selected period of time, and wherein the pH adjustment of the mixed liquor to below 6 or the maintenance of the pH of the mixed liquor below 6 gives rise to an increase in chemical and/or thermal stability of the PHA in the biomass.
