The role of probiotic Lactobacillus acidophilus ATCC 4356 bacteriocin on effect of HBsu on planktonic cells and biofilm formation of Bacillus subtilis

In the absence of HBsu, purified bacteriocin from L. acidophilus ATCC 4356 was more effective in inhibiting growth of B. subtilis BM19 planktonic cells as well as biofilm formation. The presence of HBsu on the other hand led to increased biofilm formation.
