ARC-Plant Protection Research Institute

Researcher at the Microbiology and Plant Pathology Division of the the ARC-Plant Protection Research Institute. Currently involved in the South African Rhizobium Culture Collection (SARCC) section , at the Nitrogen Fixation Unit. Research projects being undertaken include isolation and characterization of rhizobia for nodulation and nitrogen fixation in various legumes; Screening of rhizobia for the secretion of siderophores; study of the nodulation competitiveness of commercial rhizobial strains with indigenous rhizobial soil populations using the gusA  reporter gene expression; Molecular characterization of potentially effective nodulating rhizobia by means of polymerase chain reaction and sequencing  of the nodABC, and 16S r RNA genes ; Improvement of the South African Rhizobium Culture Collection (SARCC)data base by adding new information to the existing collections. More information on the rhizobium culture collections can be viewed at Moreover additional services are given to agricultural clients by supplying rhizobial strains and conducting rhizobium quality test for of commercial inoculants manufactured by inoculant producing companies.
