[Dynamics of growth of Haemophilus influenzae serotype B and synthesis of capsular polysaccharide in the process of cultivation in a synthetic nutrient medium].
The dynamics of H. influenzae, serotype b, growth and synthesis of their capsular polysaccharide in the synthetic nutrient medium, proposed by Herriot for noncapsular strains, was studied using 6 strains. The growth rate of H. influenzae, serotype b, and the amount of capsular polysaccharide, synthesized in the above mentioned medium, practically were not different from those in heart-brain broth (Difco). The possibility of minimizing the composition of Herriot's medium without any adverse effect on the amount of synthesized capsular polysaccharide was shown. As the result of these studies, the expediency of the cultivation of H. influenzae, serotype b, in the synthetic medium, intended for obtaining the preparations of capsular polysaccharide, was proved.
