Fermentation Conditions and Media Optimization for Isocitric Acid Production from Ethanol by .

Isocitric acid exists in the form of four stereoisomers, of which only the -Ds-form (ICA) is a natural active compound, an intermediate of Krebs cycle, and suitable for nutritional and pharmaceutical use. In this paper, we propose a method for ICA production from ethanol by yeast . The effects of temperature, pH of the medium, and aeration on the growth of the producer VKM Y-2373 and synthesis of ICA were studied.

[Reinfusion of blood during reconstructive operations on the aortoiliac segment].

The article presents an experience with using reinfusion of autoblood in performing planned reconstructive operations on the aorto-iliac segment in 93 patients. Allogenic hemotransfusions were used to fill up the blood losses in the control group of 82 patients. The postoperative period was shown to be more favorable in patients with reinfusion of autoblood.
