Short communication: Resazurin reducing time as an indicator of Bradyrhizobium viable cell count
(1998-01-01)
A method based on the use of resazurin (RSZ) is described to determine the number of viable Bradyrhizobium japonicum cells in culture medium. The observation of RSZ reduction can be done spectrophotometrically or visually. ...
Use of lipopolysaccharides to characterize Bradyrhizobium spp.
(1996-09-01)
Three methods of extraction of lipopolysaccharide (LPS) were compared-the conventional hot phenol-water method with 40% phenol, a modified form of this method using 10% phenol, and the hot saline method. Good recovery of ...
Towards a two-dimensional proteomic reference map of Bradyrhizobium japonicum CPAC 15: Spotlighting "hypothetical proteins".
(Proteomics, Weinheim, v. 10, n. 17, p. 3176-3189, Sept. 2010., 2010)
Electrophoretic patterns of lipopolysaccharides and antigenic analysis of soybean bradyrhizobia
(1999-01-01)
Several serological methods have been used for the characterization and identification of soybean bradyrhizobia. However, some problem were non-reactivity of certain strains and cross-reactivity among others. Since ...
Caracterização de rizóbios (Bradyrhizobium japonicum) e produtividade da soja
(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 1998-01-01)
Fez-se um estudo de campo sobre a competição e a dinâmica de ocupação de sítios de nodulação de estirpes de Bradyrhizobium japonicum naturalizadas ou inoculadas em sementes. O ensaio foi instalado em Latossolo Vermelho ...
Analysis of Two Polyhydroxyalkanoate Synthases in Bradyrhizobium japonicum USDA 110
(American Society for Microbiology, 2013-07)
Bradyrhizobium japonicum USDA 110 has five polyhydroxyalkanoate (PHA) synthases (PhaC) annotated in its genome: bll4360 (phaC1), bll6073 (phaC2), blr3732 (phaC3), blr2885 (phaC4), and bll4548 (phaC5). All these proteins ...
Ensifer (Sinorhizobium) fredii Interacted More Efficiently than Bradyrhizobium japonicum with Soybean
(Science Domain International, 2015-01)
Aims:The purpose of this work was to compare the efficiency of Bradyrhizobium japonicum and Ensifer fredii to infect and develop nodules on soybean. Furthermore we also evaluated the competitive ability of both species and ...
Structure and biological activities of lipochitooligosaccharide nodulation signals produced by Bradyrhizobium japonicum USDA 138 under saline and osmotic stress
(Springer, 2013-08)
The establishment of a symbiotic interaction involves a signal exchange between the host legume (flavonoids) and the nitrogen-fixing rhizobia (nodulation factors (NFs)). Likewise, abiotic stress conditions, such as salinity ...
