Abstract

In order to investigate the combined effect of potassium sorbate and sodium benzoate and the synergistic effect of sodium chloride on bacterial cell growth inhibition, Bacillus subtilis was cultured with or without shaking in tryptone-glucose-yeast extract broth containing 0.1% potassium sorbate and/or 0.03% sodium benzoat, which are equivalent to half of the maximum permissible levels, respectively. The combined treatment of the two preservatives did not show any synergistic effect of tne growth inhibition of B. subtilis. Addition of 2% sodium chloride, however, showed remarkable synergistic effect on the growth inhibition of the bacterium by potassium sorbate.

Bacillus subtilis의 생육 억제에 미치는 보존료의 병용효과 및 식염과의 상승효과를 조사하기 위하여 tryptone glucose-yeast extract 액체배지에 potassium sorbate와 sodiun bnzoate를 각각 최고허용농도의 1/2인 0.1%, 0.03%로 처리하고 이에 미생물의 내염성 기준도인 2% 식염을 첨가하여 진탕배양(4시간) 또는 정치배양 (4일)하면서 생육 상태를 조사한 결과, 두 보존료의 상승효과가 정치 및 진탕배양에서 모두 나타나지 않았으나 potassium sorbate와 식염의 병용처리구에서는 상승효과가 현저하게 나타났다.
