摘要
为研究浒苔多糖粗提物、浒苔多糖硒的抑菌活性,本试验以硫酸黏杆菌素、林可霉素、黄芪多糖和酵母细胞壁多糖为对照品,采用药敏试验检测浒苔多糖粗提物、浒苔多糖硒对大肠杆菌、沙门氏菌和金黄色葡萄球菌的抑菌活性。结果表明:10~100 mg/mL浓度的浒苔多糖粗提物对大肠杆菌、沙门氏菌、金黄色葡萄球菌均未产生抑菌作用,浓度为20、50、100 mg/mL的浒苔多糖硒对金黄色葡萄球菌的抑菌圈和抑菌活性分别为6 mm(-)、8 mm(+)、18 mm(++),对大肠杆菌、沙门氏菌未产生抑菌作用。
The purpose of this experiment was to investigate the antibacterial activity of extract of polysaccharide from Brassica oleracea and polysaccharide Se of Brassica.Using colistin sulfate,lincomycin,astragalus polysaccharide and yeast cell wall polysaccharide as the reference substance,the susceptibility test was used to detect the antibacterial activity of the crude polysaccharide extract of caninus sphagnum polysaccharide and canola polysaccharide against Escherichia coli,Salmonella and Staphylococcus aureus.active.The results showed that 10 ~ 100 mg/mL of crude polysaccharide had no antibacterial activity against Escherichia coli,Salmonella and Staphylococcus aureus.The concentration of 20,50,100 mg/mL of enteromorpha polysaccharides selenium Staphylococcus aureus inhibition zone and antibacterial activity were 6 mm(-),8 mm(+),18 mm(++),no antibacterial effect on E.coli and Salmonella.
