Control of Wall Band Splitting in Streptococcus faecalis

Phospholipids 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...

Hydroxylysine metabolism in Streptococcus faecalis.

aureus, and Streptococcus faecalis

SYNOPSIS The incidence of trimethoprim resistance in coliforms and multiresistant strains of Staphylococcus aureus isolated in Bristol from 1970 to 1972 is low-2-3 and 1 0% respectively. The resistance is probably intrinsic; there is no evidence that it is R-factor or plasmid mediated. A single mechanism that confers resistance to both trimethoprim and sulphamethoxazole has not been detected. N...

Protoplast membrane of Streptococcus faecalis.

Shockman, Gerald D. (Temple University School of Medicine, Philadelphia, Pa.), Joseph J. Kolb, Bohdan Bakay, Margaret J. Conover, and Gerrit Toennies. Protoplast membrane of Streptococcus faecalis. J. Bacteriol. 85:168-176. 1963.-The membrane fraction of Streptococcus faecalis (ATCC 9790) was isolated and purified, by a variety of procedures, from cultures that were grown under closely controll...

Studies of the formation of peptide cross-links in the cell wall peptidoglycan of Streptococcus faecalis.

A method was developed to label specifically the glycan chains of the cell wall peptidoglycan of Streptococcus faecalis ATCC 9790 with [14C]acetate. The formation of peptide cross-links (a) during exponential growth, (b) after valine starvation and wall thickening, and (c) during regrowth after 2 hours of valine starvation, was studied using continuous, pulse and pulse-chase labeling of the pep...
