Maintenance of pH 7.0 during the fermentation period favors accumulation of high-molecular polysaccharide-containing components, the so-called lipopolysaccharide-protein and polysaccharide-lipid complexes, in the capsules and culture medium. Increased pH of the culture medium to 8.0 reduced the period of exponential growth and the yield of polysaccharide-containing complexes as compared to the optimal conditions. Maintenance of pH 5.5 suppressed the culture growth and polysaccharide production… Expand
