Abstract

Five kinds of saprogenic bacteria were isolated from the red ginseng extract product and identified as Bacillus subtilis, Bacillus sp., Paenibacillus sp., Micrococcus sp., and Pseudomonas sp. by 16S rDNA analysis. Some of the isolated strains were able to grow even at $45^{\circ}C$ which are presumed originated from the raw ingredient of red ginseng extract. All of the isolated strains did not show the hemolytic activity, the diarrhea-inducing activity, and the vascular permeability enhancing activity, indicating that these strains are not pathogenic.

홍삼 추출액 제품의 변패원인균을 분리동정하고 생화학적 특성 및 병원성 유무를 판단하였다. 분리된 5가지의 균주는 각각 Bacillus subtilis, Bacillus sp., Paenibacillus sp., Micrococcus sp., Pseudomonas sp.로 동정되었으며, 이 중 Bacillus subtilis와 Paenibacillus sp., Micrococcus sp.는 홍삼 추출액의 원재료로부터 기인한 내생포자를 형성하는 내열성 균주로 추정되었다. 분리된 군주 대부분은 낮은 염도와 중성 pH 조건에서 잘 자라며, 영양요구성이 단순한 호중온성 세균들이었다. 또한 용혈성과 설사유발성을 나타내지 않았으며, 흰쥐 (rat)를 이용한 피부혈관 투과성 항진작용 실험에서도 음성을 나타내어, 수행한 실험 결과 내에서는 분리된 5균주 모두 병원성이 없는 것으로 판단되었다.
