Abstract

Licheva, T., M. Badalova, V. Savov, Y. Evstatieva and D. Nikolova, 2013. Study of the antibacterial activity of bacterial strains from genus Bacillus against the phytopathogenic Xanthomonas vesicatoria. Bulg. J. Agric. Sci., Supplement 2, 19: 77–79

 

The aim of this study was to determine the activity of 17 newly isolated strains from genus Bacillus against the phytopathogenic bacterium Xanthomonas vesicatoria. These strains were cultivated in liquid nutrient medium for 36-48 hours to produce antibacterial substances. The antibacterial activity was tested by the agar diffusion method. It was determined that 7 of the tested strains showed antibacterial activity against the test phytopatogen.

Key words: antibacterial activity, Xanthomonas vesicatoria, phytopathogenic bacteria
