In this study, isolation and characterization of potassium solubilizing bacteria (KSB) have been carried out which could solubilize a substantial amount of potassium (K) following incubation with mica. Five KSB, isolated from banana and chilli rhizosphere were identified by 16S rDNA sequence analysis. The identified bacteria were Klebsiella sp. and Bacillus cereus. The isolates had K solubilization potential within the range of 76.3–78.42% compared to control along with significant drop in pH (4.62–4.86). The study reveals the exploitation of Klebsiella sp. and B. cereus as potential K solubilizing biofertilizers.Keywords
