From Plants to Microbes: Bioprospecting Phytobiotics for Next-Generation Natural Products

Dear Colleagues,

With growing concerns over the use of antibiotics and other synthetic chemicals, regarding the development of resistance and their persistence in the environment, phytobiotics represent promising alternatives in the search for sustainable and effective solutions to global challenges in plant and animal agriculture, aquaculture, and human healthcare. Bioactive compounds derived from plants offer a rich reservoir of natural products with antimicrobial, antioxidant, growth-promoting, and immunomodulatory properties that can serve as eco-friendly alternatives to synthetic chemicals. Phytobiotics are gaining attention in agriculture as biopesticides against harmful pathogens, while preserving beneficial soil microbes, enhancing crop resilience and productivity. Their use aligns with integrated pest management strategies and supports the transition toward organic and regenerative farming practices. They also show promising potential in human healthcare, as they have been used for combating multidrug-resistant (MDR) pathogens, a growing concern in clinical settings. Additionally, their antioxidant properties help mitigate oxidative stress, contributing to overall health and disease prevention.

Therefore, plant extracts offer natural scaffolds for developing new antimicrobial drugs. With continued research and responsible sourcing, these products could redefine how we manage pathogens, enhance agricultural practices, and develop next-generation therapeutics. This Special Issue aims to explore sustainable and effective solutions against microbial pathogens in both agricultural setups and human health. It will highlight methodologies for isolating and characterizing bioactive compounds, screening for antimicrobial or antioxidant activity, evaluating their toxicity, and developing new formulations and products. These efforts can be combined with innovative approaches in genomics, metagenomics, and metabolomics that may further accelerate the discovery of novel phytobiotics with targeted functions. In this context, the Special Issue welcomes reviews, original research articles, and short communications.

We look forward to your valuable contribution.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Microorganisms is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
