Research has been initiated at MSIRI to investigate means of reducing the dependence of the sugar industry on inorganic fertilizers especially nitrogen. In that context, the contribution of biological nitrogen fixation is being examined. Attempts have been made to isolate bacterial species involved in this process. Preliminary findings are presented on the isolation, distribution and characterisation of two important diazotrophic bacteria namely Herbaspirillum and Gluconacetobacter spp known to be involved in N-fixation in several sugar cane producing countries. Herbaspirillum spp have been found to be widely distributed and more frequently encountered compared to Gluconacetobacter spp which were restricted to abandoned fields. The potential of the isolates collected, to fix nitrogen, has been gauged by the acetylene reduction assay (ARA) and results showing they have the ability to fix nitrogen are encouraging. | |
