Total 116 bacteria were isolated, wherein 42 isolates showed prominent efficiency of K mobilization, from which, 17 prominent cultures were selected on the basis of the highest zone of solubilization on Aleksandrov agar supplemented with mica. Isolate M-2 gave the highest potash solubilizing index 8.0 and K release 21.41 μg/ml at 4 days after inoculation in Aleksandrov broth. All the 17 KMB isolates exhibited organic acid and capsular polysaccharides production out of which 14 isolates were positive for acidic exo-polysaccharides.en-USnullThesis
