FEMS Microbiology Letters prioritizes concise papers that are worthy of rapid publication due to their originality, broad interest, and contributions to new developments in microbiology. The journal covers all aspects of microbiology, including virology. The impact factor for 2019 was 1.987, and it ranked 98/135 in microbiology according to the JOURNAL CITATION REPORTS (source: Clarivate, 2020). The journal is divided into eight sections: Physiology and Biochemistry (including genetics, molecular biology, and 'omics' studies), Food Microbiology (related to food production and biotechnology to prevent spoilage and foodborne pathogens), Biotechnology and Synthetic Biology, Pathogens and Pathogenics (including medical, veterinary, plant, and insect pathogens, particularly those related to food safety, excluding viruses), Environmental Microbiology (including ecological physiology, ecological genomics, and meta-omics studies), Virology (viruses infecting any living organism, including bacteria and archaea), Taxonomy and Systematics (for publishing new taxa, taxonomic reclassifications, and reviews on taxonomic properties), and Professional Development (including education, training, CPD, research assessment frameworks, research and publication metrics, best practices, career development, and the history of microbiology). If you are unsure which section is most suitable for your manuscript, especially in the case of interdisciplinary research, we recommend contacting the editor-in-chief via email before submission. Our scope includes any type of microorganism—members of both bacteria and archaea, as well as microbial members of eukaryotes (yeasts, filamentous fungi, microalgae, protozoa, slime molds, etc.) and all viruses.
