WebOct 28, 2024 · The disruption step seeks to break or dissolve the membranes and cell wall [also known as non-PHA cellular materials (NPCM)] to enable the extraction of the PHA granules, but sometimes this step must be combined with heating or cooling processes or with a surfactant to improve the final extraction (pretreatment) [ 33 ]. WebSolvent extraction of PHA is widely used in laboratories to prepare small quantities of high molecular weight PHA. It has also been used for PHA recovery at pilot-scale and large-scale, to a limited success. Only a few solvents are able to dissolve PHA macromolecules, particularly those of large molecular weight with a high content of short ...
