Phytopathogenic Pseudomonas Growth Inhibition by Tartaric Acid New Derivatives

The Metabolism of Tartaric Acid by a Pseudomonas. a New Pathway.

Many micro-organisms can utilize tartaric acid for growth. The only well-established reaction sequence for its dissimilation is that first proposed by Barker (1936) for the breakdown of (+ )-tartaric acid by Aerobacter aerogenre in which oxaloacetic and pyruvic acids are formed. By this sequence, tartrate is dehydrated to oxaloacetate, which in turn is usually decomposed so rapidly to pyruvate ...

Inhibition of growth of urinary type calcium hydrogen phosphate dihydrate crystals by tartaric acid and tamarind

Urinary stone is one of the oldest and the most common afflictions in humans, animals and birds. A number of people suffer from urinary stones. Brushite or calcium hydrogen phosphate dihydrate (CHPD) crystals are frequently found in urinary stones. Many fruits contain high amount of tartaric acid. Therefore, the effect of tartaric acid on the growth of CHPD crystals is presented in this article...

Growth rate inhibition of phytopathogenic fungi by characterized chitosans

The inhibitory effects of fifteen chitosans with different degrees of polymerization (DP) and different degrees of acetylation (FA) on the growth rates (GR) of four phytopathogenic fungi (Alternaria alternata, Botrytis cinerea, Penicillium expansum, and Rhizopus stolonifer) were examined using a 96-well microtiter plate and a microplate reader. The minimum inhibitory concentrations (MICs) of th...

Stereoselective radical reactions of some tartaric and glyceric acid derivatives.

[reaction: see text] Free radicals generated by the decarboxylation of dimethoxydioxanecarboxylic acids derived from L-(+)-tartaric acid and L-glyceric acid added to some maleimides and acrylates with high stereoselectivity. This method provides easy access to some chiral building blocks.
