Physiological and biochemical properties of the natural rhizospheric association of Klebsiella terrigena E6 and Bacillus firmus E3 were studied. It was demonstrated that this association fixed actively molecular nitrogen at a rate of 110 nmol ethylene per 1 mg protein per h. The dynamics of bacterial population in the association and in pure cultures were studied. The properties of this association depended on the ratio of its components; the maximal nitrogen fixation was recorded at a content… Expand
Selection of mixed inoculants exhibiting growth-promoting activity in rice plants from undefined consortia obtained by continuous enrichment
Test the hypothesis that isolating and characterizing bacterial suspensions (undefined consortia) from the root/rhizosphere of rice will contribute to the selection of mixtures of rhizobacteria with better growth-promoting activity of rice plants and found continuous enrichment in NFB medium is a good strategy.

Plant genotype and nitrogen fertilization effects on abundance and diversity of diazotrophic bacteria associated with maize (Zea mays L.)
The hypothesis that plant genotype and fertilization conditions should be taken into account when searching for N-fixer inocula is supported. Expand
Rhizobacterial consortium mediated aroma and yield enhancement in basmati and non-basmati rice (Oryza sativa L.).
The study highlights the potential of E. hormaechei and L. xylanilyticus in plant growth, yield and aroma enhancement in basmati and non-basmati rice varieties. Expand
Restoration of Degraded Pasture Soils on the Basis of EM Associations
The aim of this research was to isolate, identify, and study nitrogen-fixing root nodule bacteria and select the most promising among them for developing EM associations, which are being tested under the field conditions on the degraded pasture soils of Kazakhstan. Expand
Microbial Consortia


The Klebsiella pneumoniae cytochrome bd' terminal oxidase complex and its role in microaerobic nitrogen fixation.
The deduced amino acid sequences support the proposal that His 19, His 186 and Met 393 provide three of the four axial ligands to the Fe of the three haems in the oxidase complex, and suggest formate dehydrogenase-O may be involved in supplying electrons to a respiratory chain terminated by the bd-type oxidase.

Degradation of 4-aminobenzenesulfonate by a two-species bacterial coculture
The mutualistic interactions in a 4-aminobenzenesulfonate (sulfanilate) degrading mixed bacterial culture were studied and growth was found and the proportion of both strains moved towards an about equal value of about 3:1. Expand
Comparison of Two Cellulomonas Strains and Their Interaction with Azospirillum brasilense in Degradation of Wheat Straw and Associated Nitrogen Fixation
When introduced into sterilized soil, the Cellulomonas sp.-Azospirillum brasilense association was more effective in nitrogen fixation at a pH of 7.0 than at the native soil pH (5.6), also true of the indigenous diazotrophic microflora of this soil. Expand
Enhancement of specific nitrogenase activity inAzospirillum brasilense andKlebsiella pneumoniae, inhibition inRhizobium japonicum under air by phenol
Specific nitrogenase activity inAzospirillum brasilense ATCC 29145 in surface cultures under air is enhanced from about 50nmol C2H4·mg protein-1·h-1 to 400 nmol C 2H4 by the addition of 1 mM phenol, with a small reduction of the growth of the cells by the phenol added. Expand
Nitrogen-fixation by Azospirillum brasilense Cd is promoted when co-cultured with a mangrove rhizosphere bacterium (Staphylococcus sp.)
The N 2 -fixing ability of A. brasilense Cd increased significantly when grown in mixed culture with the non-N 2 fixing bacterium Staphylococcus epidermidis, but not with Micrococcus lylae , both isolated from mangrove roots. Expand
Alkaline Growth pH-Dependent Increase of Respiratory and NADH-Oxidation Activities of the Facultatively Alkaliphilic Strain Bacillus lentus C-125
Levels of respiratory and NADH-oxidation activities of the organism are dependent on the growth pH, and higher than those reported previously in alkaliphilic Bacillus spp. Expand
