A bacterium possessing high ability to solubilize potash was isolated from the rhizosphere of
black pepper. On the basis of biochemical and 16S rDNA sequence analysis, the bacterium was
identified as Paenibacillus glucanolyticus strain IISRBK2. The optimal medium composition and
cultural conditions for the isolation of P. glucanolyticus were sucrose 5.0 g, Na2HPO4 2.0 g,
MgSO4.7H2O 2.0 g, FeCl3 0.005 g, CaCO3 0.1 g and wood ash 1.0 g at pH 7.5 at 30oC. The strain
was also evaluated for plant growth and potassium (K) uptake of black pepper in soil artificially
treated with 0.5,1 and 1.5g K kg-1 soil in the form of wood ash. In this study, wood ash was used
as a source of K which contained 53.1 g Kg-1 K of which 4.5% was in insoluble form. Inoculation
with strain P. glucanolyticus was found to increase tissue dry mass (ranging from 37.0% to 68.3%)
of black pepper in 1g K kg-1wood ash amended soil. In the soil treated with 0.5 -1.5 g K kg-1, K
uptake in live bacterium inoculated black pepper plants increased by 125.0-184.0% compared to
uninoculated control.
