undefined Helicobacter pylori 의 생육억제에 대한 유산균, 난황항체 및 목이버섯의 상승효과

2013 
The substances of lactic acid bacteria (LAB) isolated feom Kimchi and Tarak, L. mesenteriodes LAB kw5, and S. thermophilus LAB KW15 were investigated for growth effect of Helicobacter pylori with IgY and Auricularia auricula. Inhibition of H. pylori was confirmed at LAB KW5 and KW15 supernatants. Interestingly, anti-H. pylori substance in LAB KW5 and KW15 supernatants were sensitive to lipase, but insensitive to protein hydrolase and carbohydrate hydrolase. The inhibition zone toward H. pylori was not shown with the lipase-treated supernatants. Therefore, there seemed to be lipid-like substances in the cultures. By the analyses with gas chromatography, undecanoic acid (C11:0), palmitic acid (C16:0), stearic acid (C18:0), and oleic acid (C18:1) were detected at the culture substances from L. mesenteroides LAB KW5 and S. thermophilus LAB KW15, and more eicosadienoic acid (C20:2) from L. mesenteroides LAB KW5. Anti-H. pylori substances of LAB with IgY and A. auricula extract were analyzed for inhibition effect of H. pylori. The inhibition increased more by the range from 57% to 86% by the mixture. The substances with IgY and A. auricula extract showed more effective inhibition of H. pylori than single or double trials.
