Abstract

Biofilms are the structure microbial that attach to different surfaces and enclave microorganisms in a matrix composed, protecting them from harsh conditions, including immune effectors and antibiotics. Therefore, this study aimed to assess the anti-biofilm activity of lavender, cloves, eucalyptus, rosemary, thyme, and oregano commercial essential oils, known for their biocidal properties against Gram-positive and Gram-negative ESKAPE isolates, exhibiting multiple drug resistance. The most efficient proved to be the oregano, thyme, and clove essential oils, which exhibited the lowest minimal biofilm eradication concentrations values against all bacterial species. Although lavender, eucalyptus, and rosemary had a weaker effect than the first three oils, they have also inhibited biofilm development at concentrations low enough to be considered effective. This experimental approach may open new perspectives for developing efficient strategies to combat the emergent threat of antibiotic resistance and to control the formation of microbial biofilms, being also a valuable source of bioactive compounds and new anti-biofilm drugs.

几种香料及药用植物精油抗菌活性的研究

生物膜是附着在不同表面的微生物结构，并将微生物包裹在基质中，保护它们免受恶劣条件的影响，包括免疫效应物和抗生素。因此，本研究旨在评估薰衣草、丁香、桉树、迷迭香、百里香和牛至商业精油的抗生物膜活性，这些精油以其对革兰氏阳性和革兰氏阴性ESKAPE分离株的生物杀灭特性而闻名，并表现出多重耐药性。最有效的是牛至、百里香和丁香精油，它们对所有细菌的最小生物膜根除浓度值最低。虽然薰衣草、桉树和迷迭香的效果比前三种精油弱，但它们在浓度低到足以被认为有效的情况下也能抑制生物膜的发育。该实验方法可能为开发有效的策略来对抗抗生素耐药性的新威胁和控制微生物生物膜的形成开辟了新的视角，也是生物活性化合物和新的抗生物膜药物的宝贵来源。

期刊介绍： Biointerface Research in Applied Chemistry is an international and interdisciplinary research journal that focuses on all aspects of nanoscience, bioscience and applied chemistry. Submissions are solicited in all topical areas, ranging from basic aspects of the science materials to practical applications of such materials. With 6 issues per year, the first one published on the 15th of February of 2011, Biointerface Research in Applied Chemistry is an open-access journal, making all research results freely available online. The aim is to publish original papers, short communications as well as review papers highlighting interdisciplinary research, the potential applications of the molecules and materials in the bio-field. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible.
