ABSTRACT:
Substantially pure, pyrogen-free beta-1,3-glucan is produced by cultivating Euglena cells in a defined growth medium and under specified conditions that provide a cell mass comprising 70% to 90% beta-1,3-glucan on a dry weight basis, separating the cell mass from the super-natant, extracting the cell mass with methanol and chloroform, acid-washing the extracted cell mass, and washing the acid-treated material with water.
