Arils from six pomegranate (Punica granatum L.) varieties grown in the Mediterranean region of Turkey were tested for their antimicrobial properties by the agar diffusion and minimum inhibitory concentration (MIC) methods against seven bacteria: (Bacillus megaterium DSM 32, Pseudomonas aeruginosa DSM 9027, Staphylococcus aureus Cowan 1, Corynebacterium xerosis UC 9165, Escherichia coli DM, Enterococcus faecalis A10, Micrococcus luteus LA 2971), and threefungi (Kluvyeromyces marxianus A230, Rhodotorula rubra MC12, Candida albicans ATCC 1023). It has been observed that the pomegranate aril extracts had antimicrobial effect on all microorganisms, giving inhibition zones ranging in size from 13 to 26 mm. The MIC values for active pomegranate extracts ranged between 30 and >90 microg/mL. The results obtained appeared to confirm the antimicrobial potential of the Punica granatum varieties.
采用琼脂扩散法和最低抑菌浓度(MIC)法,对生长于土耳其地中海地区的6个石榴(Punica granatum L.)品种的假种皮进行了抗菌性能测试,受试菌株包括7种细菌:(巨大芽孢杆菌DSM 32、铜绿假单胞菌DSM 9027、金黄色葡萄球菌科万1型、干燥棒状杆菌UC 9165、大肠杆菌DM、粪肠球菌A10、藤黄微球菌LA 2971)以及3种真菌(马克斯克鲁维酵母A230、深红酵母MC12、白色念珠菌ATCC 1023)。据观察,石榴假种皮提取物对所有微生物均有抗菌作用,抑菌圈大小在13至26毫米之间。活性石榴提取物的MIC值在30至>90微克/毫升之间。所得结果似乎证实了石榴品种的抗菌潜力。
