Abstract

Tourtellotte, Mark E. (University of Connecticut, Storrs), Harold J. Morowitz, and Phil Kasimer. Defined medium for Mycoplasma laidlawii. J. Bacteriol. 88:11–15. 1964.—A defined medium for the pleuropneumonia-like organism Mycoplasma laidlawii B is described in which absolute requirements for coenzyme A and longchain fatty acids were demonstrated. This organism did not require cholesterol or macromolecules of high molecular weight, but did show a growth requirement for peptides. Optimal growth in the basal medium was obtained in the presence of two purified peptides from crystalline ribonuclease, one of which has the amino acid sequence threonine - threonine - glutamine - alanine - asparagine-lysine, and the other lysine-glutamic acid-threonine-alanine-alanine-alanine-lysine. Continuous, but suboptimal, growth was obtained with the single ribonuclease peptide: lysine-glutamic acid-threonine-alanine-alanine-alanine-lysine.
