Lactic acid with high nisin-productivity and method of selecting the same

摘要

Per selection by the bacteria grown in synthetic medium containing bacteriocins by lactic acid bacteria is used as an indicator of resistance to a non-bacteriocin or bacteriocin producing new age, when the growth in liquid medium by the culture medium supernatant ash 1mL 6,800IU to obtain a lactic acid bacterium having the above age Shin-producing ability, and by using the relevant culture in food or feed to improve the preservability of food or feed. ; New Age, Lactobacillus, Lactococcus lactis, bacteriocins, age, new production capacity, selection, batch culture
