The goal of this study was to isolate and characterize the wild yeast strains from the gut of earthworm(Eisenia andrei). The 19 yeast strains isolated from 5 gut of earthworm samples from Nanji water regeneration center in Goyang-si, Gyeonggi-do, Korea. Among them, 16 strains were recorded and 3 strains, Yarrowia deformans YP242 (=KACC48778), Sporidiobolus pararoseus YP66 (=KCTC27963) and Naganishia liquefaciens YI9 (=KACC48948) were recorded for the first time in Korea. The microbiological characteristics of these previously unrecorded yeasts were investigated. All three strains were oval-shaped, convex and smooth. However, they showed some differences in colony color and result of carbon assimilation assays. YP242 was white-colored and assimilated glycerol, L-arabinose and N-acetyl-D-glucosamine as carbon sources. YP66 was red-colored and assimilated D-Saccharose. YI9 was white-colored and positive for 2-keto-D-gluconate assimilation.
