Gel-forming capsular polysaccharide of Rhizobium leguminosarum and Rhizobium trifolii

Carbohydrate Research, 1983
Extraction of cell pellets of several R. leguminosarum and R. trifolii strains with M NaOH at room temperature released an anthrone-positive material which, on neutralisation of the extract, precipitated as a gel. The polysaccharide could also be extracted with hot water.

Chemolithotrophy in Rhizobium

1981
The first pure cultures of Rhizobium species were described by Beijerinck in 1888 who surface disinfected nodules from Vicia, Lathrus and Trifolium and cultured the nodule endophytes on gelatin plates containing plant extracts, sucrose, and asparagine. Since this pioneering discovery, Rhizobium species have been considered chemoorganotrophs and always ...

Interspecific transformation in Rhizobium

Archiv f�r Mikrobiologie, 1967
Two characters, “Penicillin resistance” and “fructose utilizing ability”, were transferred in the recipient Rhizobium cowpea (source—Ground nut roots) with the help of the DNA extracted from Rhizobium phaseoli culture (source—French bean roots). The recipient culture enters the logarithmic growth phase at the end of 60 min.

The Genus Rhizobium [PDF]

, 1981
Bacteria responsible for the formation of morphologically defined nodules on the roots of members of the family Leguminosae constitute the genus Rhizobium. The common capacity of such symbiosis to reduce dinitrogen to ammonia and to incorporate this product into the nitrogen metabolic stream of the host plant gives the genus a place of outstanding ...

Detection of uptake hydrogenase in Rhizobium leguminosarum and Rhizobium meliloti

Zentralblatt für Mikrobiologie, 1988
Summary A rapid colour test is described which is selective for uptake hydrogenase (Hup+) activity under ex planta conditions. The test is based on decolonization of methylene blue. The decolonization time is a function of Hup activity. It is possible to select single colonies showing different Hup activities. A known Hup+ strain of R.

Discrimination of Rhizobium japonicum, Rhizobium lupini, Rhizobium trifolii, Rhizobium leguminosarum and of bacteriods by uptake of 2-ketoglutaric acid, glutamic acid and phosphate

Archives of Microbiology, 1976
Rhizobium strains (one each of Rh. japonicum, Rh. lupini, Rh. leguminosarum) take up 2-ketoglutaric acid in general much faster and from lower concentrations in the medium than strains of Escherichia coli, Bacillus subtilis and Chromobacterium violaceum. A strain of Enterobacter aerogenes, however, is more similar to some Rhizobium strains.

Advances in Rhizobium Research

Critical Reviews in Plant Sciences, 2002
Rhizobia are well known for their capacity to establish a symbiosis with legumes. They inhabit root nodules, where they reduce atmospheric nitrogen and make it available to the plant. Biological nitrogen fixation is an important component of sustainable agriculture, and rhizobial inoculants have been applied frequently as biofertilizers. In this review

Selection for cheating across disparate environments in the legume-rhizobium mutualism.

Ecology Letters, 2014
The primary dilemma in evolutionarily stable mutualisms is that natural selection for cheating could overwhelm selection for cooperation. Cheating need not entail parasitism; selection favours cheating as a quantitative trait whenever less-cooperative ...

Inoculation of the nonlegume Capsicum annuum (L.) with Rhizobium strains. 1. Effect on bioactive compounds, antioxidant activity, and fruit ripeness.

Journal of Agricultural and Food Chemistry, 2014
Pepper (Capsicum annuum L.) is an economically important agricultural crop and an excellent dietary source of natural colors and antioxidant compounds.
