Centrolobium tomentosum is a tropical legume tree indicated for functional and structural restoration of riparian areas. This study was conducted to characterize the rhizobia isolated from nodules of C. tomentosum in situ and to determine their capacity of renodulation, in an experimental area of land rehabilitation in the Rio Doce valley. Nodulation potential to inoculation with 2 selected fas...

By complementing cell-free extracts of Pseudomonas putida F1/pSMMO20 with purified soluble methane monooxygenase (sMMO) components of Methylosinus trichosporium OB3b, the low cloned-gene sMMO activity in the recombinant strain was found to be due to incomplete activity of the hydroxylase component. To address this incomplete activity, additional sMMO-expressing strains were formed by transferri...

Naturally occurring nitrogen-fixing symbionts from root nodules of caragana (Caragana arborescens) growing in central Saskatchewan were isolated following surface sterilization of caragana root nodules and squashing and spreading of the contents on yeast extract - mannitol medium. The symbiotic nature of the strains was confirmed following inoculation onto surface-sterilized C. arborescens seed...

in this study, the ability of 32 rhizobium strains (26 strain of sinorhizobium meliloti (sm)), 4 strains of rhizobium leguminosarum biovar phaseoli (rlp) and 2 salt tolerance strains of rhizobium leguminosarum  biovar viciae (rlv) for use of acc as individual nitrogen source in rmm media was evaluated. based on the results, 25 strains were found positive for acc-deaminse, and strains according ...

Chickpea (Cicer arietinum L.) is the world’s third most vital food legume after beans and peas in production level. Yet, its productivity last decade has been declined, it contended that usual native soil rhizobial populations are insufficient/ineffective N2-fixation. Rhizobium inoculation of seed may substitute costly N-fertilizers provide a useful way achieving sustainable production. Hence, ...

Salinity is a major detrimental factor for plant growth and crop productivity that could be alleviated by the use of promoting bacteria (PGPB) with protective role in such stressful conditions. In this study, four native strains genus Pseudomonas were isolated from both strongly saline soil rhizosphere soybean plants grown slightly soil. These isolates able to tolerate high NaCl concentration, ...

Soybean has the potential to bring significant benefits in diversified cropping systems, which could help restructuring soil fertility and allow smallholders increase grain yield. Rhizobium inoculation improves biological nitrogen fixation (BNF) legume crops assists resource-poor farmers yield at lower financial costs. The efficacy of symbiotic bacteria on legumes can also be improved...

Abstract The article presents the results of studied effect biological nitrogen fixation on yield, forage value, protein and oil productivity soybean varieties belonging to northern ecotype (Mageva, Okskaya Svetlaya), depending water supply. Under conditions Central Non-Chernozem Region, have been proved provide maximum yield 3.05 t/ha; content – 43.51%; fat 20.67%; 1322 kg/ha; essential amino ...
