METHODS OF EXTRACTING POLYHYDROXYALKANOATES FROM PHA-CONTAINING BACTERIAL CELLS

摘要

The present disclosure provides a method to extract polyhydroxyalkanoates (PHAs) from PHA-containing bacterial cells. The method extracts solid PHAs from the bacteria by using a base and a surfactant to lyse the cells, and two or more solvents to purify the PHAs released from the lysed cells.
