Abstract
Barnes, Isabel J. (Cornell University, Ithaca, N. Y.), H. W. Seeley, and P. J. VanDeMark. Nutrition of Streptococcus bovis in relation to dextran formation. J. Bacteriol. 82:85-93. 1961.-Three nutritional types of Streptococcus bovis were encountered. Minimal media for their growth are described. Transferable growth in defined media was always accompanied by dextran production and the nutrition for dextran production could not be distinguished from the minimal nutritional requirements of the organism for growth. Measurable, free CO(2) was evolved from a complex medium during the growth of S. bovis. Several compounds were found to replace partially the CO(2) requirement of the species. When fractured cell preparations containing S. bovis dextran were employed as antigens, rabbits failed to yield sera which would precipitate S. bovis or leuconostoc dextrans.
