Application of Lactococcin Bz and Enterocin Kp against Listeria Monocytogenes in Milk as Biopreservation Agents. AKADEMIAI KIADO RT.1588-25350139-3006https://dx.doi.org/10.1556/066.2016.45.4.4https://hdl.handle.net/11480/3538This study was performed to evaluate the effect of lactococcin BZ and enterocin KP against Listeria monocytogenes ATCC 7644 in skim (0.1%), half (1.5%), and full fat (3.0%) UHT milks. The milk samples were inoculated with L. monocytogenes at the level of approximately 2.60, 4.76, and 6.45 log CFU ml(-1), and then treated with various concentrations (400, 800, 1600, or 2500 AU ml(-1)) of lactococcin BZ, enterocin KP, or their combination (1: 1). Lactococcin BZ at 400-2500 AU ml(-1) level displayed strong antilisterial activity, and decreased the viable cell numbers of L. monocytogenes to an undetectable level in all types of milk samples during the entire storage periods at 4 degrees C or 20 degrees C. Enterocin KP also had a high antilisterial effect, but it decreased as both the fat content of milk and inoculation amount of L. monocytogenes increased.eninfo:eu-repo/semantics/openAccessBacteriocinLactococcin BZEnterocin KPListeria MonocytogenesMilkArticle45448649210.1556/066.2016.45.4.42-s2.0-84994086894N/AWOS:000387847500004Q4
