Review summarizes both literature and own experimental data on the application of arachidonic acid (AA, C20:4 omega-6) as an elicitor of the plant defense reactions to phytopathogens. The elicitation activity of AA was shown to depend considerably on its concentration. High AA concentrations (over 10-5 M) induce necrosis of plant tissues and accumulation of(More)
Production of d S-threo-isocitric acid (ICA) by yeast meets serious difficulties since it is accompanied by a simultaneous production of citric acid (CA) in significant amounts that reduces the yield of desired product. In order to develop an effective process of ICA production, 60 yeast strains of different genera (Candida, Pichia, Saccharomyces,(More)
The process of succinic acid (SA) production represents the combination of microbial synthesis of α-ketoglutaric acid from rapeseed oil by yeast Yarrowia lipolytica VKM Y-2412 and subsequent decarboxylation of α-ketoglutaric acid by hydrogen peroxide to SA that leads to the production of 69.0 g l−1 of SA and 1.36 g l−1 of acetic acid. SA was isolated from(More)
The effects of pH, aeration, and temperature on the growth of fungal strain Mortierella alpina LPM-301 and the synthesis of lipids and arachidonic acid in glycerol-containing medium were studied. Arachidonic acid production in the stationary growth phase was found to depend considerably on the pH value; it reached the optimum at pH 6.0 and was irreversibly(More)
