A Study on the Cellular Fatty Acid Profiles of Listeria spp. Isolated from Foods
일반식품에서 분리된 Listeria spp.의 지방산 조성에 관한 연구
Abstract
The distribution of Listeria spp. in various foods and its fatty acid composition were examined. A total 60 samples of dairy products(15), seafoods(20), meat products(18), factory waster(2), and salades(5) were tested. Listeria spp. was found 10 samples, showing about 16.7% detection ratio; dairy products 0(0%),,seafoods 1(5%), meat product 7(38.9%), and factory wastes 2(100%). Whereas L. welshimeri was isolated from meat products 1(5.6%) and factory wastes 1(50%). The cellular fatty acid composition determined by gas chromatography was found not to differ among L. innocua isolated from food has similar fatty acid profiles when grown at 3
