The present invention provides a fungal penny room Solarium Solid term (Penicillium solitum) proliferation, or accession No. DSM32094 the fungal penny Solarium breather chamber bikom paekteom (Penicillium deposited in the deposit with accession No. DSM32093 It relates to the growth of brevicompactum) the Lactobacillus buffer tumefaciens of momentum (Lactobacillusfermentum) species having the ability to inhibit at least 50%. The inhibitory activity can be determined by methods including the following: (1) for producing a fermented milk product by the following: (a) the Lactobacillus buffer momentum to at least 10 7 CFU / g concentration in the milk, and starter culture to inoculating, (b) will fermenting until the pH reached 4.6, and (c) will be crystallized and the fermented milk by the addition of agar (2) to a fermented milk agar solidified P. Solid term or generated in at least one point to a concentration of 500 spores / spot of P. breather bikom paekteom and incubated at 25 ℃ for 7 days (3) Solid-term or P. P. breather bikom determines the maximum diameter of the colony formed by proliferation of paekteom, Lactobacillus buffer represents the diameter as a percentage of the maximum diameter, and is formed under the same conditions except for the absence of the momentum strain to determine the percent inhibition by. The present invention also relates to a process for producing fermented milk products using the composition, the tumefaciens containing the tumefaciens, and the resulting product obtained.본 발명은 수탁번호 DSM32093으로 기탁된 진균 페니실리움 솔리텀(Penicillium solitum)의 증식, 또는 수탁번호 DSM32094로 기탁된 진균 페니실리움 브레비콤팩텀(Penicilliumbrevicompactum)의 증식을 적어도 50% 억제하는 능력을 갖는 락토바실러스 퍼멘텀(Lactobacillus fermentum) 종의 박테리움에 관한 것이다. 상기 억제 활성은 다음을 포함하는 분석법으로 결정될 수 있다: (1) 다음에 의해 발효유 제품을 제조하는 것: (a) 우유에 적어도 107 CFU/g 농도로 락토바실러스 퍼멘텀을, 및 스타터 배양물을 접종하는 것, (b) pH가 4.6에 도달할 때까지 발효시키는 것, 및 (c) 한천을 첨가하여 발효유를 고화시키는 것 (2) 한천 고화된 발효유에 P. 솔리텀 또는 P. 브레비콤팩텀의 적어도 하나의 점을 500 포자/점의 농도로 생성시키고, 25℃에서 7일 동안 인큐베이
