[Consumption of hydrocarbons by psychrotolerant degrader strains].

Oil-oxidizing microorganisms have been sampled in various regions of Siberia and used in strain associations, which degrade n-alkanes of oil from various fields by 64-92% after 6 days of growth in a wide temperature range. These strains are salt-tolerant and psychrotolerant. They are compatible with aboriginal soil microflora. Promising results have been obtained in experiments on growing plants on oil-polluted soil purified with a biodegrader of this series.

[Immunoenzyme test-system for detection of glycyrrhizic acid]. / Immunofermentnaia test-sistema dlia vyiavleniia glitsirrizinovoi kisloty.

An experimental enzyme immunoassay test kit was developed for detecting glycyrrhizic acid (GA) during pharmacokinetic investigations. This method was used to determine the GA content in the blood plasma of mice and guinea pigs after intraperitoneal and intravenous injections. The results of the GA determination using the new test kit agree with the data obtained by HPLC.
