Defined medium for growth of two transformable strains of Diplococcus pneumoniae.
The classic bacterial transformation system, and one of the two most thoroughly studied systems, is Diplococcus pneumoniae. Transformation systems seem to offer a unique opportunity to study, at the molecular level, the hereditary material, deoxyribonucleate, and the molecular units of the organism it determines. Unfortunately this study has been retarded by a lack of well defined biochemical m...
متن کاملEvaluation of an improved chemically defined medium for the culture of Diplococcus pneumoniae.
In 1942, Bernheimer et al., described a partially defined medium which supported growth of the ,3-hemolytic streptococcus. Starting with this medium, Adams and Roe (1945) devised a chemically defined medium which was adequate for the culture of pneumococcus. Improvement in the medium of Adams and Roe (Hoeprich, 1955) resulted from: omission of copper and calcium; addition of L-tyrosine; increas...

Defined medium for growth of Haemophilus influenzae.
A chemically defined medium (MI(c)) is described in which cells of Haemophilus influenzae Rd grow rapidly (generation time, 35 +/- 5 min) and reach a stationary level of 10(10) cells/ml. Our strain of cells grown in this medium developed high levels of competence when transferred to another medium designed for that purpose. Conditions governing the total development of competence in this organi...

Bacteriol. 91:601-603. 1966.-A method for the quantitation of neuraminidase in the presence of N-acetylneuraminic acid aldolase is described. The neuraminidase content of Diplococcus pneumoniae was found to be dependent on the media employed for...
