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 http://www.wdcm.nig.ac.jp/CCINFO/CCINFO.xml?968. 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.
