As agricultural practices become more sustainable, adopting more sustainable practices will become even more relevant. Searching for alternatives to chemical compounds has been the focus of numerous studies, and bacteriocins are tools with intrinsic biotechnological potential for controlling plant diseases. We continued to explore the biotechnological activity of the bacteriocin Gluconacin from , PAL5 strain, by investigating this protein's antagonism against important tomato phytopathogens and demonstrating its effectiveness in reducing bacterial spots caused by . In addition to this pathogen, the bacteriocin Gluconacin demonstrated bactericidal activity in vitro against and pv. , agents that cause bacterial wilt and bacterial spots, respectively. Bacterial spot control tests showed that Gluconacin reduced disease severity by more than 66%, highlighting the biotechnological value of this peptide in ecologically correct formulations.
随着农业实践变得更加可持续，采用更多可持续的做法将变得更加重要。寻找化学化合物的替代品一直是众多研究的重点，而细菌素是具有控制植物病害内在生物技术潜力的工具。我们继续探索来自PAL5菌株的细菌素葡糖菌素的生物技术活性，通过研究这种蛋白质对重要番茄植物病原体的拮抗作用，并证明其在减少由[病原体名称未给出]引起的细菌性斑点方面的有效性。除了这种病原体外，细菌素葡糖菌素在体外还对分别导致青枯病和细菌性斑点的[病原体名称未给出]和[病原体名称未给出]pv.[具体名称未给出]表现出杀菌活性。细菌性斑点控制试验表明，葡糖菌素使病害严重程度降低了66%以上，突出了这种肽在生态正确配方中的生物技术价值。
