Short communication: Resazurin reducing time as an indicator of Bradyrhizobium viable cell count
(World Journal of Microbiology and Biotechnology, 1998-01-01) [Artigo]
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. ...
Electrophoretic patterns of lipopolysaccharides and antigenic analysis of soybean bradyrhizobia
(World Journal of Microbiology and Biotechnology, 1999-01-01) [Artigo]
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 ...
Use of lipopolysaccharides to characterize Bradyrhizobium spp.
(Soil Biology and Biochemistry, 1996-09-01) [Artigo]
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 ...
