The production of fatty acids by a gram-negative coccus

The production of fatty acids by a gram-negative coccus.

We have isolated from the rumen of the sheep an anaerobic Gram-negative coccus which ferments glucose, fructose, maltose, mannitol, sorbitol and DL-lactate with the production of hydrogen and carbon dioxide, acetate, propionate, n-butyrate, npentanoate and n-hexanoate (Elsden, Gilchrist, Lewis & Volcani, 1951). Since it is our intention to discuss the taxonomic position of this organism in a se...

Antibacterial activity of sphingoid bases and fatty acids against Gram-positive and Gram-negative bacteria.

There is growing evidence that the role of lipids in innate immunity is more important than previously realized. How lipids interact with bacteria to achieve a level of protection, however, is still poorly understood. To begin to address the mechanisms of antibacterial activity, we determined MICs and minimum bactericidal concentrations (MBCs) of lipids common to the skin and oral cavity--the s...

Lipopolysaccharide layer protection of gram-negative bacteria against inhibition by long-chain fatty acids.

Growth, amino acid transport, and oxygen consumption of Escherichia coli and Salmonella typhimurium are inhibited by short-chain (C(2)-C(6)) but not by medium or long-chain fatty acids (C(10)-C(18)) at concentrations at which these processes are completely inhibited in Bacillus subtilis. The resistance of gram-negative organisms is not correlated with their ability to metabolize fatty acids, si...

examining the relationship between fear of negative evaluation and communication strategies by iranian efl learners

the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
