The specificity of glutamine for growth of Streptococcus haemolyticus)

GLUTAMINE was established as an essential nutrient for Streptococcus haemolyticus by Mcllwain et al. [1939] and its importance in growth of other bacteria, notably pneumococcus, was shown by Fildes & Gladstone [1939]. It is involved in many other biological materials and processes, which makes desirable the determination of the specificity of the glutamine structure in producing these effects. The present results of attempted growth of streptococcus in the presence of compounds related to glutamine show that glutamine is extremely specific in this respect.
