ABSTRACT:
In some embodiments, this invention relates to a method that includes contacting a PHA with an aprotic catalyst to form an ester. The ester has only one monomer unit from the PHA. In certain embodiments, this invention relates to a method that includes treating a PHA-containing non-lyophilized biomass to form an ester, and removing at least some of the ester from the biomass.
