The cellular fatty acid composition of Halomonas salina, a moderately halophilic bacterium grown at different salt concentrations, is reported. Fatty acids C16:0 and C18:1 were major components and significant amounts of C16:1, C18:0 and cyc-C19:0 were also detected. The results showed clear chemotaxonomic relationships with recognized members of the genus Halomonas. The salt concentration grea...

The link between dietary salt intake and the development of hypertension in the saltsensitive Dahl strain of rats remains elusive. There is evidence that Dahl salt-sensitive rats (DS) produce less vasodilator and natriuretic prostaglandins in response to salt loading than do control saltresistant rats (DR), although the reason for this blunted response is unknown. We examined the effects of chr...

Amounts of iron released from iron pots vary from meal to meal. The effects of salt, pH, and organic acids as iron chelators were studied. Maize (corn) porridges were prepared in a cast iron pot from maize flour and 12 aqueous solutions with different pH (3.7 or 7.2), salt contents (0% or 0.5% NaCl), and organic acids (1% lactate, 1% citrate, or none). Salt had no effect, but acidic pH or organ...

We have studied the cellular mechanisms underlying adaptation to salt stress in a newly isolated osmo- and salt-tolerant strain of the yeast Yarrowia lipolytica. When cells are incubated in the presence of 9% NaCl, a rapid change in their size and shape is observed. Salt stress is accompanied by an increase in the intracellular level of glycerol, free amino acids (notably proline and aliphatic ...

-A new general method for the preparation of 2-alkyl-pipecolic acids has been developed. The syntheses of 2-methyl-, 2-benzyland cis-6-methylpipecolic acids are described. ( ) S and (+)R-2-methylpipecolic acids were resolved by fractional crystallization of the quinine salt of their N-carbobenzoxy derivative. Isolation of (-)S-cis-6-methylpipecolic acid required the use of 4-phenylbenzyloxycarb...

The objective of this ongoing work is to perform a detailed systematic study of organic salt formation through a series of designed experiments. We have identified a set of descriptors that describe molecular properties relevant to salt formation. For the initial experiments, a collection of salt forming acids have been assembled using the Cambridge Structural Database and their descriptor valu...

Salt metathesis and BFX (boron–fluoride exchange) of BF4− with boronic acids generates RBF3− derivatives, thus showing the solvolytic lability that enables its use as a fluorinating agent, even though many highly reactive reagents employ non-reactive counteranion. In their Research Article (e202215371), David M. Perrin co-workers report synthesis derivatives via salt reaction using series MBF4 ...

Barley (Hordeum vulgare L.) is the most salt-tolerant cereal crop and has excellent genetic and genomic resources. It is therefore a good model to study salt-tolerance mechanisms in cereals. We aimed to determine metabolic differences between a cultivated barley, Clipper (tolerant), and a North African landrace, Sahara (susceptible), previously shown to have contrasting root growth phenotypes i...
