Food Microbiol — The minimum inhibitory concentration of the bacteriocin was performed using broth microdilution method proposed by Steinberg [ 20 ]. Listeria monocytogenesas indicator bacteria, were grown in brain heart infusion BHI broth Oxoid, United Kingdom. According to the inhibition zone from the crude bacteriocin purified from the supernatant, the bacteriocin started to produce at 8 hours of incubation and reached optimum production at 18 hours incubation period. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. New York, NY: Springer, 15— · Purification of Bacteriocin. Bacteriocin produced by L. plantarum J23 was purified via a three-step procedure, including ammonium sulfate precipitation, cation-exchange chromatography, and RP-HPLC. Initially, the cell-free supernatant containing bacteriocin was precipitated by 40, 50, 60, 70, and 80% ammonium sulfate. The results showed that 80 Cited by: characterization and purification of a bacteriocin produced by leuconostoc mesenteroides subsp. cremoris a thesis submitted to the graduate school of natural and applied sciences of middle east technical university by halİl dÜndar in partial fulfillment of the requirements for the degree of doctor of philosophy in biotechnology september Purification ofthe bacteriocin.
