초록

S.B, P.S, C.P를 각각 처리한 배지에 배양된 진균류(Aspergillus phoenicis, Rhizopus acidus, Candida albicans)에서 원형질막을 분리하였다. 원형질막 단백질의 함량과 특성을 대조구와 비교하였다. A. phoenicis의 생장은 S.B 처리구에서 평균 64.0%가 감소하였다. R. acidus의 생장은 P.S 처리구에서 평균 69.0%가 감소하였다. 또한 C. albicans의 생장도 S.B 처리구에서 평균 59.5%의 감소를 나타내었다. 여러 진균세포 원형질막에 함유된 단백질의 함량은 S.B 처리구에서 평균 41.0%, 41.7%, 59.5%가 각각 억제되었다. A. phoenicis의 원형질막 단백질의 변화 양상은 처리구에서는 배양 1일째, 2일째는 대조구와 비슷한 경향을 나타내었다. 그러나 배양 1일째 $116\;KD{\sim}97\;KD$ 밴드는 거의 사라졌고 $45\;KD{\sim}29\;KD$ 밴드는 희미하게 관찰되었다. R. acidus는 S.B 처리구에서 배양 중간기부터 $116\;KD{\sim}97\;KD$ 밴드가 소실되었으며, P.S 처리구와 C.P 처리구는 배양초에 소실되기 시작하여 배양 36시간에는 완전히 소실되었다. C. albicans에서는 $116\;KD{\sim}97\;KD$ 밴드가 대조구와 비교하여 배양초에 소실되기 시작하였고 $66\;KD{\sim}45\;KD$밴드는 배양 96시간에 희미하게 나타났다. 특히 C.P 처리구에서는 배양 96시간에 완전히 소실되었다.

Abstract

Plasma membrane from the fungal cells (Aspergillus phoenicis, Rhizopus acidus, Candida albicans) treated with sodium benzoate (S.B), potassium sorbate (P.S) and calcium propionate (C.P) during the cultivation were separated. The contents and patterns of plasma membrane proteins compared with those of the control. The growth of A. phoenicis was decreased by the average 64.0% in the S.B treatment. That of R. acidus was inhibited by the average 69.0% in the P.S treatment. Also, That of C. albicans was showed the deminution of the average 59.5% in the S.B treatment. The contents of protein involved in the plasma membrane of the each fungal cells were inhibited the average 41.0%, 41.7% and 59.5% in the S.B treatment, respectively. In case of A. phoenicis, the changes in the protein pattern involved in the plasma membraneshowed the aspect similar to the control on the 1st day and 2nd day of cultivation in the treatment group, but $116\;KD{\sim}97\;KD$ band almost disappeared in the 5th day of cultivation, and $45\;KD{\sim}29\;KD$ band was uncleared through the cultivation. In S.B treatment group R. acidus was showed the loss of $116\;KD{\sim}97\;KD$ band from the middle stage of cultivation and P.S, and C.P treatment group were started the loss at the early stage and completely lost at the 36 hours of cultivation. In C. albicans, $116\;KD{\sim}97\;KD$ band were started the loss at the early stage to compare with the control and $66\;KD{\sim}45\;KD$ band were dimmed at the 96 hours of cultivation. Especially, the C.P treatment group were perfectly lost at the 96 hours of cultivation.
