Abstract

Plants are a largely untapped source of antibiotic-producing microorganisms. In this study, 237 bacteria were isolated from the leaf surface of field-grown . Screening 49 Gammaproteobacteria isolates for antibiotic activity identified eighteen isolates of interest. These findings underscore the plant phyllosphere as a valuable reservoir for discovering novel antibiotics.

摘要

植物是产生抗生素的微生物的一个很大程度上未被开发的来源。在本研究中，从田间种植的植物叶片表面分离出237种细菌。对49株γ-变形菌分离株进行抗生素活性筛选，鉴定出18株有研究价值的分离株。这些发现强调了植物叶际作为发现新型抗生素的宝贵资源。
