Leuconostoc mesenteroides와 Lactobacillus brevis, Lactobacillus fermentum을 무주스에 starter로 0.3%(106 cfu/)첨가하여 에서 7일, 15에서 20일, 5에서 36일동안 숙성하면서 단독, 또는 혼합 배양에 의한 무주스의 가공특성을 조사하였다. 무주스를 에서 숙성할 경우 유산균수는 혼합배양이 단독배양보다 높게 계수 되었으나 낮은 온도 (15~5)에서는 접종균주에 따라 증감의 차

Lactic aicd bacteria(LAB)는 전통적으로 식품의 발효과정 중에 사용되는 미생물이다. Lactic acid bacteria를 이용한 bacteriocinogenic culture와 lactic acid bacteria에서 생산되는 산물은 식품의 부패에 원인이 되는 미생물과 병원성균에 대한 생육억제효과을 지니고 있다. 이러한 이유로 생선제품, 유제품. 육제품과 발효되지 않은 냉장식품 등의 식품저장에 lactic acid bacter
