Abstract: The antibacterial effect of Gutian Tremella fuciformis polysaccharides on five common pathogenic bacteria was tested using the antibacterial circle test. The results showed that a 1.87 μg·mL-1 Tremella fuciformis polysaccharide solution had a certain inhibitory effect on Pseudomonas aeruginosa, Salmonella paratyphi B, and Escherichia coli, but a 1.87~151.42 μg·mL-1 Tremella fuciformis polysaccharide solution had no significant inhibitory effect on Staphylococcus aureus and Candida albicans.

Keywords: antibacterial circle test; Gutian Tremella fuciformis; pathogenic bacteria; bacteriostatic effect

銀耳(Tremella fuciformis),也稱白木耳、雪耳等,是擔(dān)子菌門真菌銀耳的子實(shí)體,顏色多為白色或淡黃色,呈葉狀、凝膠狀,分布廣泛,特別是在熱帶地區(qū),常見于闊葉樹的腐木上,在我國福建省、浙江省、廣東省、安徽省、四川省和江蘇省等地多有分布[1-2]。(剩余5656字)
