IRON-REDUCING MICRORGANISMS INTO SUPERDEEP VULCANIC ROCKS ^{[№ 12 ' 2011]}
The first iron-reducing bacteria (IRB) to be studied into Ural superdeep well (SG-4) rocks with a microorganisms of the sulfur and carbon cycles. A wide spread of IRB was demonstrated as well as their possible participation in biogenic formation of magnetic mineral among which the magnetite is more abundant into SG-4 rocks. A permanent presence of sulfate-reducing bacteria was supported, thiobacteria were discovered.

AUXINE PRODUCTION BY ENDOPHYTIC BACTERIA FROM UNDERGROUND ORGANS OF DACTYLORHIZA MACULATA (L.) SOO (ORCHIDACEAE) ^{[№ 12 ' 2011]}
For the first time it was established, that the bacteria of the genus Bacillus which were isolated from the underground organs of Dactylorhiza maculata, the representative of family Orchidaceae inhabiting temperate climate region of Russia, have produced phytohormone 3-indolylacetic acid (IAA). The IAA level found out in cultural liquid of 12 from 15 bacterial strains was within the limits 0,3 — 29 mkg/ml and depended on strain.
