Somatic antigens of Bradyrhizobium japonicum, Rhizobium sp. (Cicer arietinum) and Rhizobium sp. (Leucaena leucocephala) were prepared as standard, single-species type from cultured cells. Equal numbers of the cells of these rhizobia were then combined to obtain a mixed-rhizobial-species antigen preparation. Rabbits were immunized either with the standard, single-species type or with the mixed-r...

evaluation of genetic diversity is a considerable approach to screen within indigenous rhizobial population for compatible, highly effective strains, which can be further utilized as rhizobial inoculums. genetic diversity of rhizobium isolates from three clover species grown in soil samples of seven different geographical regions in iran was investigated by repetitive extra genomic palindromic ...

Growth and survival of two rhizobial strains, Rhizobium leguminosarum bv. trifolii, and Mesorhizobium ciceri, were used to evaluate residues from the cork industry as potential carriers for production of rhizobial inoculants. A peat-based carrier was used as a control. 41 days after inoculation, the number of viable bacteria was high, about 109 bacteria g-1 for all carriers. Rhizobial survival ...

The aim of this study was to determine the effects of a bacterial inoculant and chemical additives on nutrient composition, in vitro degradation, total loss, aerobic stability, microbiological quality, and fermentative profile of sugarcane silage. Treatments were distributed to forty-eight mini-silos in a 2 × 4 factorial arrangement: two levels of microbial inoculant (INO, 0 or 4 g/t of fresh s...

Globins (Glbs) are proteins widely distributed in organisms. Three evolutionary families have been identified in Glbs: the M, S and T Glb families. The M Glbs include flavohemoglobins (fHbs) and single-domain Glbs (SDgbs); the S Glbs include globin-coupled sensors (GCSs), protoglobins and sensor single domain globins, and the T Glbs include truncated Glbs (tHbs). Structurally, the M and S Glbs ...

Inoculation of phosphate-solubilizing microorganisms along with rock phosphate is known to enhance the available P from soil. The success of such solubilization is largely dependent on the ability of the inoculant strain to survive under adverse environmental conditions. In this context, liquid inoculants are gaining importance and are becoming popular with longer shelf-life. In the present inv...

Inoculation of forage and grain legumes with rhizobia is an important process to maximize biological N2 fixation capacity in these crops. Inoculation has the potential of increasing dry matter yield, N yield, and residual N levels. However, yield responses to inoculation are not universal in the region. In fields that have previously grown the same grain legume crop (i.e. contain an endemic rhi...

We aimed to verify the changes in the microbial community during bioremediation of gasoline-contaminated soil. Microbial inoculants were produced from successive additions of gasoline to municipal solid waste compost (MSWC) previously fertilized with nitrogen-phosphorous. To obtain Inoculant A, fertilized MSWC was amended with gasoline every 3 days during 18 days. Inoculant B received the same ...

The persistence of the biocontrol agent Pseudomonas fluorescens CHA0 in the surface horizon of 12 large outdoor lysimeters planted with winter wheat, Phacelia tanacetifolia followed by spring wheat, or maize was monitored for 1 year. Soil was inoculated with a spontaneous rifampin-resistant mutant (CHA0-Rif) of CHA0, and the strain was studied by using colony counts, Kogure's direct viable coun...
