‘+’ and ‘-’ indicates sensitivity and resistance, respectively. Values in parenthesis represent the zones of inhibition of the test bacteria. A = combination of metabolite from B. proteolyticus and B. thuringensis, B = combination of metabolite from B. proteolyticus and B. cereus, C = combination of metabolite from B. thuringensis and B. cereus, D = combination of metabolite from B. proteolyticus and B. subtilis, E = combination of metabolite from B. thuringensis and B. subtilis and F = combination of metabolite from B. cereus and B. subtilis.
