Shelf life enhancement of plant growth promoting rhizobacteria using a simple formulation screening method

Plant growth promoting rhizobacteria (PGPR) are a specific group of bacteria interacting beneficially with plants. Among the known PGPRs, the species Pseudomonas fluorescens and Burkholderia pyrrocinia have been highlighted in both growth promotion and control of rice diseases. Ensuring the stability of the microorganism during production, formulation, distribution and storage has been a challenge for these species. In...

Sugarcane growth promotion by Kosakonia sp. ICB117 an endophytic and diazotrophic bacterium

The present study investigates the strain Kosakonia sp. ICB117, an endophytic, N2-fixing bacterium that belongs to a genus recently described. The bacteria were isolated from sugarcane stalks (Saccharum sp. variety SP791011) and inoculated into other sugarcane plants of the same variety. The effect of inoculation on sugarcane growth was then studied in the presence or absence of nitrate supplementation (10 mM). The...
