BACKGROUND
In Europe, and , originate large amounts of biomass, due to their need by industries and other biological control, that can be used to extract antimicrobial substances.
MATERIALS AND METHODS
Foliar aqueous, ethanolic and methanolic extracts of (Cootamundra wattle), (silver wattle), (black wattle) and (narrow-leaved black peppermint) were assessed for antimicrobial activity against , , and , using the disc diffusion method.
RESULTS
Ethanolic extracts from and showed significant (P< 0.05) antimicrobial activity. Concerning the microbial species tested, differences were found in (P< 0.01) and (P< 0.0001) extracts. These two extracts were effective mostly against , followed by . According to the antimicrobial activity classification, eucalypt and Cootamundra and silver wattles extracts (both water and ethanol) presented good efficacy against , a food poisoning agent, and moderate efficacy against the remaining microorganisms. , a Gram negative, exhibited low sensibility to all foliar extracts.
CONCLUSION
, and foliar biomass could be used to develop alternative substances in microbial control.
背景
在欧洲，由于工业和其他生物防治的需求，产生了大量可用于提取抗菌物质的生物质。
材料与方法
采用纸片扩散法，评估了金合欢（Cootamundra金合欢）、银荆（银荆）、黑荆（黑荆）和窄叶黑薄荷（窄叶黑薄荷）的叶水提取物、乙醇提取物和甲醇提取物对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌和白色念珠菌的抗菌活性。
结果
金合欢和银荆的乙醇提取物显示出显著（P<0.05）的抗菌活性。在所测试的微生物种类方面，金合欢（P<0.01）和银荆（P<0.0001）提取物存在差异。这两种提取物主要对金黄色葡萄球菌有效，其次是枯草芽孢杆菌。根据抗菌活性分类，桉树叶、金合欢和银荆提取物（水提取物和乙醇提取物）对食物中毒病原体金黄色葡萄球菌具有良好的疗效，对其余微生物具有中等疗效。革兰氏阴性菌大肠杆菌对所有叶提取物表现出低敏感性。
结论
桉树叶、金合欢和银荆的叶生物质可用于开发微生物控制的替代物质。
