Expanding the Use of a Fluorogenic Method to Determine Activity and Mode of Action of Bacillus thuringiensis Bacteriocins Against Gram-Positive and Gram-Negative Bacteria
Figure 4
Effect of bacteriocins produced by B. thuringiensis on the growth of Salmonella sp. (a) Log10 cfu mL−1 (b) optical density measured at 660 nm. The five bacteriocins were added in the middle of the logarithmic phase of growth curve (3 h) of Salmonella sp. culture (indicator strain) used as control (without bacteriocins). Salmonella sp. (◂); Morricin 269 (■); Kurstacin 287 (●); Kenyacin 404 (▲), Entomocin 420 (▼); Tolworthcin 524 ().
