Zinc Solubilizing Bacteria (ZSB)
- Few bacterial species in soil have the potential to solubilize insoluble zinc compounds like ZnO, ZnCO3, ZnS and sphalerite ore.
- A zinc solubilizing bacterium (Bacillus sp.) isolated from sphalerite ore enhanced the available zinc content of soil and plant uptake upon inoculation.
- For plant inoculation, bacterial inoculaare prepared by growing pure cultures of Zn solubilizing bacteria in a suitable nutrient broth. The final concentration of the bacterial suspension is adjusted to 108cfumL-1.
- Method of application:The roots ofrice seedlings are thoroughlywashed with tap water;surface sterilized in 2% NaOCl for 15 minutes and finally rinsed with sterile distilled H2O and isinoculated by soakingthem overnight in different bacterial inocula maintained at 108cfumL-1.
