Supplementary Material

A total of 31 bacterial strains, designated as R-1 to R-31, were isolated from the rhizosphere of various plants and described in table 1. None of this strain demonstrated antagonistic activity against the soft soft rot causing bacterial strain P-138. A total of 48 bacterial strains, designated as E-35 to E-82, were extracted from the endophytes of 19 different plant species from 5 different potato-farming areas of Bangladesh and presented in table 2. Only the isolates E-45 and E-65 demonstrated antagonistic activity in in vitro test. A total of 4, 3 and 12 bacterial strains were isolated from compost fertilizer (C-28-C-31), atmosphere (A-59- A-61) and BSMRAU laboratory (L-85-L-96) and are preseted in table 3. None of these bacterial isolates demonstrated antagonistic activity against the soft soft rot causing bacterial strain P-138. The species identification schemes of isolates E-45 and E-65 using various physiological and biochemical tests are presented in tables 4-6. The combined sets of identification tests strongly suggested that antagonistic function containg isolates E-45 and E-65 were belonged to Lactobacillus and Bacillus species, respectively.
