Systematic and Applied Microbiology deals with various aspects of microbial diversity and systematics of prokaryotes. It focuses on Bacteria and Archaea; eukaryotic microorganisms will only be considered in rare cases. The journal perceives a broad understanding of microbial diversity and encourages the submission of manuscripts from the following branches of microbiology:
Systematics: Theoretical and practical issues dealing with classification and taxonomy, i.e. • New descriptions or revisions of prokaryotic taxa, including in particular descriptions of not-yet cultured taxa in the category Candidatus, • innovative methods for the determination of taxonomical and genealogical relationships • evaluation of intra-taxon diversity through multidisciplinary approaches • identification methods.
Applied Microbiology: polyphasic studies combining multiple methods yielding in-depth data on the diversity and function of particular clades of Bacteria and Archaea in all aspects of agricultural, food, and industrial microbiology, including water and wastewater treatment. Also these studies must have a focus on prokaryotic systematics.
Comparative biochemistry and genomics: studies concerning biochemical/metabolic and genomic diversity of cultured as well as yet-uncultured Bacteria and Archaea.
Ecology: polyphasic descriptions of the microbial diversity and community composition of natural and man-made ecosystems; studies quantifying the size, dynamics, and function of prokaryotic populations; innovative research on the interaction of Bacteria and Archaea with each other and their biotic and abiotic environments. The description of candidate taxa is highly encouraged but should be based on high quality metagenomic information, as well as the in situ identification of the target bacterial or archaeal populations.
