Endospore forming bacterial distribution on the ‘EC’ SFS and NFS slopes.

1The endospore forming bacterial fraction was isolated as described in Material and Methods.2ACC (1-Aminocyclopropane-1-carboxylate) medium was composed of salts for P. polymyxa minimal medium there the nitrogen source is replaced with ACC.3Biofilm formation was estimated as described in Material and Methods. The isolates with OD >1 were considered as biofilm formers.4Halophilic growth was determined in the medium containing 2 M NaCl (see Material and Methods).5P solubilization was estimated using NBRIP medium (see Material and Methods). The colonies with index >2 were considered as P solubilizers.
