摘要:
A process for reducing the protein content and preserving the capsular polysaccharide content in a complex cellular Streptococcus pneumoniae lysate broth prior to purification is described. Utilizing pH reduction after cellular lysis has resulted in a purified polysaccharide that consistently meets the protein specification, and higher recovery yields of polysaccharide during the purification process.
