Abstract
A process for recovering and purifying polyhydroxyalkanoates from a cell culture may include: (a) acidifying the culture to obtain a pH value less than or equal to 6, and submitting the culture to a cell fractionation treatment using high-pressure homogenization at a temperature greater than or equal to 10° C. and less than or equal to 80° C. to obtain a suspension; (b) basifying the suspension to obtain a pH value greater than or equal to 8; (c) diluting the suspension and submitting the diluted PHA suspension to tangential filtration to obtain a concentrated suspension as retentate and an aqueous phase as permeate; (d) submitting the concentrated suspension to bleaching; (e) diluting the suspension after the bleaching and submitting the diluted bleached suspension to tangential filtration to obtain a concentrated bleached suspension as retentate and an aqueous phase as permeate; and/or (f) submitting the concentrated bleached suspension to drying.
