The Optimum Hydrogen Ion Concentration for the Growth of Pneumococcus
نویسندگان
چکیده
1. The optimum hydrogen ion concentration for the growth of the various types of pneumococcus is a pH of about 7.8. 2. The limiting hydrogen ion concentrations for the growth of pneumococcus are a pH of 7.0 and a pH of 8.3. 3. Phosphates used in adjusting reactions of media retard growth if present in a concentration greater than 0.1 molecular. 4. Culture media for pneumococci should, therefore, have an initial reaction between a pH of 7.8 and 8.0 and a total salt concentration not exceeding 0.1 M.

Hydrogen Ion Concentration of Cultures of Pneumococci of the Different Types in Carbohydrate Media
1. The optimum hydrogen ion concentration for growth of pneumococcus is pH 7.8. 2. In broth cultures growth of pneumococcus continues until a final hydrogen ion concentration of about pH 5.0 is reached, if sufficient fermentable carbohydrate' (above 0.4 per cent) is present. Apparently this acidity is sufficient in itself to stop growth. 3. If less carbohydrate is present in the medium growth c...
متن کاملStudies on the Enzymes of Pneumococcus
1. Pneumococci contain an intracellular enzyme of marked lipolytic activity as measured by the acid liberated by its action on tributyrin. 2. Enzyme-containing solutions may be prepared by dissolving pneumococci in bile, or by extraction by other means. 3. The optimum reaction for maximum activity of the endolipase is about pH 7.8, which coincides with the optimum hydrogen ion concentration for...
متن کاملThe Relation of the Pneumococcus to Hydrogen Ion Concentration, Acid Death-point, and Dissolution of the Organism
1. In the growth and death of the pneumococcus in fluid media containing 1 per cent glucose the production of acid is the most important bactericidal factor. 2. 1 per cent glucose bouillon cultures of the pneumococcus allowed to grow and die out usually reach a final acidity of a pH of about 5.1. 3. At a hydrogen ion concentration of about 5.1 or higher, the pneumococcus does not survive longer...
متن کاملThe Relation of the Pneumococcus to Hydrogen Ion Concentration, Acid Death-point, and Dissolution of the Organism.* by Frederick
Lord 1 has called attention to the probable importance of an increase in the hydrogen ion concentration in the pneumonic lung in inhibiting the growth of the pneumococcus and favoring enzymatic action. In this article we wish to elaborate certain aspects of the relation of the pneumococcus to changes in acidity. The hydrogen ion concentrations were determined by the colorimetric method with sta...
متن کاملThe Effects of Acidity upon the Growth of Pneumococcus in Culture Media Containing Proteins
In the presence of animal fluids or their protein constituents, Type I Pneumococcus survived and multiplied at acid hydrogen ion concentrations which in the plain broth were bactericidal for these organisms. Minimal numbers of these cells readily produced pneumococcus growth in serum broth when adjusted at hydrogen ion concentration as great as pH 5.5 with hydrochloric, or to pH 6.5 with acetic...
