Antibacterial activity of the isolated probable antagonistic bacteria was tested in vitro against the previously identified most common and most virulent soft rot causing bacterial strain Ecc P-138. Only two isolates E-45 and E-65 significantly inhibited the in vitro growth of Ecc P-138. Physiological, biochemical, and carbon source utilization tests identified isolate E-65 as a member of the genus Bacillus and the isolate E-45 as Lactobacillus sp. The stronger antagonistic activity against Ecc P-138 was found in E-65 in vitro screening and storage potatoes. E-65 reduced the soft rot infection to 22-week storage potatoes of different varieties by 32.5-62.5 in model experiment, demonstrating its strong potential to be used as an effective biological control agent for the major pectolytic bacteria Ecc. The highest (62.5) antagonistic effect of E-65 was observed in the Granola and the lowest (32.7) of that was found in the Cardinal varieties of the Bangladeshi potatoes. The findings suggest that isolate E-65 could be exploited as a biocontrol agent for potato tubers. 2014-01-13T04:05:09Z 2014-01-13T04:05:09Z 2012 Article The Scientific World Journal, vol. 2012, 2012, pages 1-6 1537-744X http://www.hindawi.com/journals/tswj/2012/723293/ http://dspace.unimap.edu.my:80/dspace/handle/123456789/31175 en Hindawi Publishing Corporation
