Carbohydrates are important in bacterial nutrition chiefly as sources of energy. They spare or protect nitrogenous constituents in so far as energy requirements are concerned, but they do not and ...cannot substitute for nitrogenous substances, which are indispensable for the structural requirements of the organisms. It is probable that certain members of the group also become integral parts of structural units, as for example, components of nucleins. Carbohydrates are biochemically of extreme interest in bacteriology through the relations which exist between the stereo-isomerism of members of the group having the same empiric formula, and their utilizability by various types of bacteria. Carbohydrates possess value in the classification of bacteria through the fact that a definite relationship apparently exists between the stereo-configuration of various definite groups of these substances and the ability of the organisms to ferment them. In other words, the "fermentation reactions" of many kinds of bacteria are a means of their identification. The significance of a classification of bacteria based on fermentation reactions, therefore, depends on a recognition of the relation between the space arrangement of the carbohydrate and a fundamental capacity of the cytoplasm of the microbe to dissociate it with the liberation of energy for the cell. The unerring specificity of these reactions possess theoretical interest in that a careful selection of bacteria as reagents of extraordinary delicacy opens a way for the testing of important theories relating to carbohydrates, as, for example, the formation of enols, and of tautomerism. The products of fermentation produced by a great majority of bacteria are qualitatively very similar, irrespective of the carbohydrate fermented and of the organism inciting the process. Thus, diphtheria, typhoid, colon bacilli, streptococci and staphylococci produce varying amounts of organic acid, chiefly lactic, from a great variety of sugars. The specificity of action of these bacteria, therefore, would appear to depend principally on the products arising from the utilization of protein, not only for structure but for energy as we11. The classification of bacteria, including the streptococci, therefore, on the basis of fermentation reactions makes it possible to separate them into convenient and distinct groups which have divisional value. There is no clearly discernible relationship, however, between cultural grouping based on carbohydrolysis and pathogenesis.
