ABSTRACT

LANGENFELD, M. G. (University of South Dakota, Vermillion) AND P. F. SMITH. Phosphorus distribution in pleuropneumonia-like and L-type organisms. J. Bacteriol. 86:1216–1219. 1963.—Sterol-requiring and sterol-nonrequiring pleuropneumonia-like organisms, salt-requiring and salt-nonrequiring L forms, and their parent bacteria, were analyzed for total, acid-soluble, lipid, and nucleic acid phosphorus. Total phosphorus in all types of organisms was equivalent, except for salt-requiring L forms in which it was greatly elevated. The elevated total phosphorus reflected a great increase in acid-soluble phosphorus in the salt-requiring L forms. The lipid phosphorus content of pleuropneumonia-like organisms and salt-nonrequiring L forms was significantly greater than in the other types of organisms. The nucleic acid phosphorus content of salt-requiring L forms was lower than that of all other organisms
