Special Issue Information
Dear Colleagues,
Nitrogen-fixing bacteria are a specialized group of prokaryotes that use their nitrogenase system to catalyze the conversion of dinitrogen gas (N2) into ammonia. More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle. These bacteria specifically improve the growth and development of plants by supplying them with nitrogen; therefore, their survival and proliferation require their adaptation to the rhizosphere and host plant. Based on their relationship with the host plant, nitrogen-fixing bacteria are classified as symbiotic or associative. Biological nitrogen fixation (BNF) contributes approximately 200 million tons of nitrogen to the Earth's ecosystem annually and has been applied in agricultural production for almost a century. Thus, BNF is a low-cost alternative to chemical fertilizer, and its core theory and cutting-edge technology are currently a hot topic in the study of biology.
This Special Issue entitled “Nitrogen-fixing bacteria and plant–microbe interaction” aims to present recent research on any aspect of BNF. Focal points include, but are not limited to, the following:
- Legume symbiotic nitrogen fixation;
- Non-legume nitrogen fixation;
- The interaction of nitrogen-fixing bacteria with plants;
- Synthetic biology research on nitrogen fixation.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
