Industrial applications using natural microorganism resources are being attempted in various industries. One of the most useful microorganisms is the Metschnikowia persimmonesis KCTC 12991BP which is from Calyx of Diospyros kaki. This strain is a highly anti-bacterial yeast that has recently been separated by a Korean research team for the first time. In this study, antimicrobial activity of the strain against plant-contaminated microorganisms was tested. Microorganisms that can occur in the strain and plants were cultured by pure isolation and then competition tests of them were done. As a result, these tests were established that the Metschnikowia persimmonesis KCTC 12991BP has antimicrobial activity against not only Botrytis cinerea and Fusarium oxysporum which were already been reported before, but also Fungal endophyte, Paecilomyces inflatus, Colletoirichum higginsianum, Sclerotinia sclerotiourm, and Alternaria alternata. Based on the mycostasis effects of this strain, it can be used as natural preservatives which is much more safer than chemical preservatives. Doing so will ensure the nation’s safety and furthermore, it is believed that it will be served as a first mover in the global herbal medicine market by establishing medicinal values from microorganisms separated from herbal medicine resources.
