Abstract

Butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) were tested for their effectiveness in inhibiting the growth of microorganisms. Among the test microorganisms, the growth of three yeasts (Saccharomyces cerevisiae, Kloeckera apiculata, Cryptococcus hungaricus), three bacteria (Bacillus subtilu, Lactobacillus cases, Escherichia colt) and two molds (Aspergillus oryzae. Penicillium sp.) was progressively decreased as concentrations of BHA were increased. A. oyzae was completely inhibited with 100ppm of BHA and a majority of the test microorganisms (S. cerevisiae, K. apiculata. C. hungaricus, B. subtilis, A. oryzae) were completely inhibited by 150 ppm of BHA. The growths of L. casei, E. coli and Penicillium sp. were not affected as much as those of other microorganisms by BHA. Final cell yiedls were becoming lower as the concentration of BHA increased. The growth of C. hungaricus and L. casci was slightly inhibited by BHT. Other microorganisms were not effected by the test concentrations of BHT.

Butylated hydroxyanisole (BHA)과 butylated hydroxytoluene (BHT)의 각 농도에 따른 미생물의 성장 억제 효과에 대한 연구 결과, 본 연구에서 대상으로한 미생물 중 3종의 효모 (Saccharomyces cerevisiae, Kloeckera apiculata, Cryptococcus hungaricus), 3종의세균 (Bacillus subtilis, Lactobacillus casei, Escherichia coli), 2종의 곰팡이 (Aspergillus oryzae, Penicillium sp.) 가 BHA의 농도가 증가함에 따라서 성장이 점차적으로 억제되어 BHA 500ppm에서는 성장속도가 약간 느려졌고 BHA 100ppm 에서는 더욱 느려졌으며 (A. oryzae 는 완전 억제) BHA 150ppm에서는 대부분의 미생물 (S.cerevisiae, K.apiculata, C.hungaricus, B.subtilis, A.oryzae) 의 성장이 완전하게 억제되었으나 3종의 미생물 (L.casie, E.coli, Penicillium sp.)의 성장은 약간 억제되었을 뿐이다. BHT에는 2종의 미생물 (C.hungaricus, L.casei)만이 성장이 약간 억제되었고 시험 농도 범위에서는 기타 미생물에 대한 성장 억제작용은 없는 것으로 나타났다.
