LYSOGENY IN RHIZOBIUM TRIFOLII
Canadian Journal of Microbiology, 1961A phage-like particle (phage i) found in filtrates of Rhizobium trifolii (strain RT 9) did not produce plaques but induced development of two different phages in a presumed defective lysogenic strain (RT 10). These induced phages (phages 9 and 10) differed in their host ranges and produced plaques on strains RT 9 and RT 10, respectively.

Interspecific transformation in Rhizobium
Archiv f�r Mikrobiologie, 1967Two 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.

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.

Detection of uptake hydrogenase in Rhizobium leguminosarum and Rhizobium meliloti
Zentralblatt für Mikrobiologie, 1988Summary 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.

Seven of eight Rhizobium strains survived 70° C but not 80° C for half an hour in liquid media. The proportion of cells surviving heat treatment varied with the composition of the media and the age of the cultures, but did never exceed 0.7%. It appears that this heat resistance is not an effect of sporulation, according to the classical definition of a

Transformation in Rhizobium japonicum
Archiv für Mikrobiologie, 1969The transformation of streptomycin resistance in Rhizobium japonicum was studied. The susceptible strain 211 was selected from sixty strains and one step mutant resistant to streptomycin in concentration 1 mg per 1 ml was used as the donor. The peak of the competence curve appeared at the ninth hour of growth; the frequency, when the homologous strain ...

Introduction of Rhizobium into Soils
1988Preliminary results of the common experiment designed to investigate gene transfer in the environment between introduced Rhizobium leguminosarum bv viceae RSM2004 and native strains of bacteria are reported. They show an exclusive nodulation of the pea by wild type strains, which casts some doubt on the successful introduction of the strain.

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 ...
