The replacement of chemical synthesis by environmentally friendly energy-efficient technologies for production of valuable metabolites is a principal strategy of developing biotechnological industry all over the world. In the present study, we develop a method for α-ketoglutaric acid (KGA) production from rapeseed oil with the use of Yarrowia lipolytica(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 production of α-ketoglutaric acid by yeast Yarrowia lipolytica VKMY-2412 from ethanol and its subsequent chemical conversion to succinic acid (SA) were investigated. A highly effective and environmentally friendly process of α-ketoglutaric acid production was developed using a special pH-controlling strategy, in which the titration of the culture broth(More)
Protective effect of Luteococcus japonicus subsp. casei exometabolites on the cells of transient probiotic Propionibacterium strains, Enterococcus faecium, and the yeasts Saccharomyces cerevisiae Boulardii under exposure to bile salts (BS) and acid stress was studied. The extracellular peptide reactivating factor (RF) and the peptide component of the(More)
We studied the biosynthesis of isocitric acid from rapeseed (canola) oil by the yeast Yarrowia lipolytica and its regulation. We determined a fundamental possibility for directed biosynthesis of isocitric acid by Y. lipolytica yeast, with only minimal amounts of citric acid byproduct, when grown on a medium containing canola oil. Wild type strains of Y.(More)
