Characterization of rhizobia fromLeucaena

World Journal of Microbiology & Biotechnology, 1992
Seventy-six rhizobia were isolated from the nodules ofLeucaena plants of various genotypes growing in a wide range of soil types and climatic regions. The isolates were fast-growing and acid-producing. In establishing a serological grouping for the isolates, the intrinsic antibiotic resistance (IAR) patterns to low concentrations of eight antibiotics ...

Sensitivity of Rhizobia to vanillin

Folia Microbiologica, 1974
The sensitivity of Rhizobia isolated from pea, fenugreek, gram, cowpea, urid andRhizobium meliloti, Rhizobium trifolii andRhizobium japonicum was studied in asparagine-mannitol, salt-mannitol and salt media. It was observed that Rhizobia from gram were most resistant.Rhizobium japonicum was found to be resistant up to 50 mg vanillin/100 ml.

Rhizobia: From Saprophytes to Endosymbionts [PDF]

open access: yesNature Reviews Microbiology, 2018
Rhizobia are some of the best-studied plant microbiota. These oligotrophic Alphaproteobacteria or Betaproteobacteria form symbioses with their legume hosts. Rhizobia must exist in soil and compete with other members of the microbiota before infecting legumes and forming N2-fixing bacteroids.

Adsorption of rhizobia to cereal roots

Biochemical and Biophysical Research Communications, 1978
Abstract The attachment of Rhizobium japonicum 61A89 to the roots of wheat and rice seedlings is an equilibrium process that follows a Langmuir adsorption isotherm. This model predicts a maximum of 8 × 109 viable bound bacteria per g of root. Different strains of bound rhizobia have both characteristic appearances and surface densities on the ...

Phytoremediation of Heavy and Transition Metals Aided by Legume-Rhizobia Symbiosis

open access: yesInternational Journal of Phytoremediation, 2014
Legumes are important for nitrogen cycling in the environment and agriculture due to the ability of nitrogen fixation by rhizobia. In this review, we introduce an important and potential role of legume-rhizobia symbiosis in aiding phytoremediation of ...

Salt and pH tolerance of Rhizobia

Folia Microbiologica, 1973
Salt and pH tolerance ofRhizobium strains specific forSesbania cannabina Pers., sannhemp (Crotalaria juncea L.) and soybean [Glycine max (L) Merr.] have been studied. The salt effect appeared to be ion-specific. Chlorides were more toxic than sulphates of Na, K and Mg. MgSo4 has a stimulatory effect at lower than 1.0%.

Phylogeny of Rhizobia

2000
16S rRNA sequence analyses have been used to infer the phylogenetic relationships among rhizobial species by comparison with results obtained from sequences of two alternative loci. We consider the possibility of whether a biological species approach might be useful in defining species limits in the rhizobia.
