Abstract In order to control seed-borne diseases, we obtained extracts from commercial fermented food products of Kimchi, Gochujang, Doenjang, Ganjang and Makgeolli and their suppressive effects against seed-borne diseases were studied. In addition, the suppressive effects of bacterial strains isolated from the fermented foods were screened in vitro and in vivo. Among fifty food extracts, twenty food-extracts suppressed more than 92% incidence of seedling rots in vitro and seven food extracts increased 58.3-66.8% of healthy seedling in the greenhouse. Among 218 isolates from the fermented foods, 29 isolates showing high antifungal activity against seven seed-borne fungal pathogens were selected. Among 29 isolates, 13 isolates significantly reduced seedling rot and increased healthy seedlings. Sixteen isolates with high antifungal activity and suppressive effect against sesame seedling rots were identified by 16S rRNA sequencing. Fourteen of sixteen isolates were identified as Bacillus spp. and the other two isolates from Makgeolli were identified as Saccharomyces cerevisiae. It was confirmed that B. amyloliquifaciens was majority in the effective bacterial population of Korean fermented foods. In addition, when the bioformulations of the two selected effective microorganisms, B. amyloliquifacien Gcj2-1 and B. amyloliquifacien Gcj3-1, were prepared in powder forms using bentonite, kaolin, talc and zeolite, talc- and kaolin-bioformulation showed high control efficacy against sesame seed-borne disease, followed by zeolite-bioformulation. Meanwhile control efficacy of each bentonite-bioformulation of B. amyloliquifacien Gcj2-1 and B. amyloliquifacien Gcj3-1 was lower than that of bacterial suspension of them. It was found that the selected effective microorganisms from Korean fermented foods were effective for controlling seed-borne diseases of sesame in vitro and in the greenhouse. We think that Korean fermented food extracts and useful microorganisms isolated from the extract can be used as bio-control agents for suppressing sesame seed-borne diseases based on above described results. 참깨 종자전염성 병해를 방제하기 위하여 다양한 유용미생물을 함유하는 김치, 고추장, 된장, 간장, 막걸리를 채집하여 식품 추출물을 조제하고 종자전염성병원균에 대한 억제 효과를 조사하였다. 추가로 식품유래 미생물의 참깨 종자전염성 병해 억제 효과를 in vitro 및 in vivo 조건하에서 조사하였다. 50개 식품추출물에 처리한 참깨 종자를 샤레상에 처리하였을 때 20개 식품추출물이 유묘썩음증상을 92% 이상 감소시켰고, 7개 식품 추출물 처리는 온실조건에서 지상부 출현율을 58.3-66.8% 향상시키는 것으로 나타났다. 여러 발효식품으로부터 얻은 218종의 발효미생물 중 7종의 종자전염성 병원균에 대하여 높은 항균활성을 보였던 29균주를 처리하여 종자소독효과를 검정한 결과, 20균주가 병 억제 효과가 있는 것으로 나타났다. 20균주 중 13균주는 모썩음 증상을 유의성 있게 감소시켜 건전주율을 향상시키는 것으로 나타났다. 16S rDNA region의 염기서열분석을 통해 in vitro 및 in vivo에서 항균활성 및 종자소독 효과를 보인 식품유래 유용미생물 16종에 대한 동정을 수행하였다. 그 결과 14균주는 Bacillus 속 세균으로, 막걸리로부터 분리된 2균주는 Saccharomyces 속으로 동정되었다. 발효식품에서 분리된 선발 균주는 대부분 B. amyloliquifaciens인 것으로 나타났다. 선발 균주 중 B. amyloliquefaciens Gcj2-1와 B. amyloliquefaciens Gcj3-1를 코팅제로 bentonite, kaolin, talc 및 zeolite를 첨가 혼화하여 제제화하였을 때 두 균주 공히 talc와 kaolin 제형이 억제 효과가 우수하였고 그 다음이 zeolite 제형이었다. 그러나 bentonite 제형의 경우에는 타 제형에 비해 억제 효과가 낮게 나타났다. 선발된 발효식품유래 미생물은 in vitro와 온실조건에서 참깨 종자전염성병 방제에 있어서 효과적인 것으로 확인되었다. 이상의 결과를 근거로 국내산 발효식품 추출물 및 발효식품 유래 미생물은 참깨 종자소독용 방제제로서 사용될 수 있을 것으로 생각된다.
