Relation of growth of Streptococcus lactis and Streptococcus cremoris to amino acid transport.
The maximum specific growth rate of Streptococcus lactis and Streptococcus cremoris on synthetic medium containing glutamate but no glutamine decreases rapidly above pH 7. Growth of these organisms is extended to pH values in excess of 8 in the presence of glutamine. These results can be explained by the kinetic properties of glutamate and glutamine transport (B. Poolman, E. J. Smid, and W. N. ...
متن کاملThe differentiation of Streptococcus cremoris and Streptococcus lactis by means of bacteriophage action.
Many pure cultures of lactic streptococci have been isolated at this Institute during investigations of the various problems associated with the behaviour of cheese starters in commercial factories. These cultures have been derived mainly from commercial starters consisting of mixtures of several types of streptococci. The strains most suitable for use as 'single-strain starters' have proved to...
متن کاملControl of glycolysis by glyceraldehyde-3-phosphate dehydrogenase in Streptococcus cremoris and Streptococcus lactis.
The decreased response of the energy metabolism of lactose-starved Streptococcus cremoris upon readdition of lactose is caused by a decrease of the glycolytic activity (B. Poolman, E. J. Smid, and W. N. Konings, J. Bacteriol. 169:1460-1468, 1987). The decrease in glycolysis is accompanied by a decrease in the activities of glyceraldehyde-3-phosphate dehydrogenase and phosphoglycerate mutase. Th...
متن کاملCarbohydrate Fermentation by Streptococcus cremoris and Streptococcus lactis Growing in Agar Gels.
When lactic streptococci were embedded in agar gels and incubated at 30 degrees C, the end products of carbohydrate fermentation depended on the initial cell density, which determined the subsequent distribution and size of colonies in the gel. With high initial cell densities, microcolonies formed close together and lactose and glucose were converted almost entirely to lactate. However, inocul...
