Tabor, Celia W. (National Institute of Arthritis and Metabolic Diseases, Bethesda, Md.). Stabilization of protoplasts and spheroplasts by spermine and other polyamines. J. Bacteriol. 83:1101-1111. 1962.-Spermine (10(-3)m) or spermidine prevents lysis of lysozyme-produced protoplasts of Escherichia coli W, E. coli B, and Micrococcus lysodeikticus in hypotonic media. Spheroplasts prepared by the ...

Bacteriol. 84:1094-1098. 1962.-Incubation of whole cells of Streptococcus faecalis F24 in the presence of the crystalline egg-white lysozyme and appropriate sucrose concentration resulted in the formation of discrete spherical structures. On dilut...
متن کاملSynthesis of peptidoglycan in the form of soluble glycan chains by growing protoplasts (autoplasts) of Streptococcus faecalis.
Protoplasts (autoplasts) of Streptococcus faecalis were produced by the action of native autolytic N-acetylmuramidase in the absence of added peptidoglycan hydrolases and were grown in osmotically stabilized medium containing L-[3H]lysine and D-[14C]alanine. To reduce the level of muralytic hydrolysis of glycan chains during growth, heat-inactivated cell walls were added to the medium to bind a...
متن کاملCharacterization of the presumed peptide cross-links in the soluble peptidoglycan fragments synthesized by protoplasts of Streptococcus faecalis.
Protoplasts of Streptococcus faecalis ATCC 9790 were produced with the aid of lysozyme, and the ability of these bodies to synthesize soluble, peptide cross-linked peptidoglycan (PG) fragments was examined. Lysozyme digests of PG isolated using gel filtration from the supernatant medium of protoplasts grown in the presence of [14C]acetate and L-[3H]lysine contained small amounts of PG having KD...
متن کاملPhospholipids of Streptococcus faecalis.
Autoradiograms of total lipid extracts from Streptococcus faecalis ATCC 9790, harvested in the stationary phase from a medium containing (32)P-orthophosphate, showed six major spots. The corresponding compounds were identified as diphosphatidylglycerol (possibly with a penta acyl structure); phosphatidylglycerol; a provisionally identified mixture of alanylphosphatidylglycerol and of the 2'-lys...
