Unit cell hypothesis for Streptococcus faecalis.
The mass doubling times of exponential-phase cultures of Streptococcus faecalis were varied from 30 to 110 min by omitting glutamine from a defined growth medium and providing different concentrations of glutamate (ranging from 300 to 14 mug/ml). After Formalin fixation, cells were dried by the critical point method, and carbon-platinum replicas were prepared. The surface area and volume of cel...
متن کاملEffect of inhibition of deoxyribonucleic acid and protein synthesis on the direction of cell wall growth in Streptococcus faecalis.
Selective inhibition of protein synthesis in Streptococcus faecalis (ATCC 9790) was accompanied by a rapid and severe inhibition of cell division and a reduction of enlargement of cellular surface area. Continued synthesis of cell wall polymers resulted in rapid thickening of the wall to an extent not seen in exponential-phase populations. Thus, the normal direction of wall growth was changed f...
متن کاملStudies 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...
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...

Bacteriol. 86:490-493. 1963.-l-Canavanine, a competitive inhibitor of arginine, was found to stimulate the growth of Streptococcus faecalis var. liquefaciens in the presence of arginine. This growth stimulation by canavanine wa...
