Scope
Aims, scope and focus
Geomicrobiology Journal is published by Taylor and Francis Ltd. and is in Zone 4 of Environmental Science & Ecology in the CAS Journal Ranking (2025 upgraded edition). By OpenAlex counts of its recent articles, its largest topics are Microbial Community Ecology and Physiology, Methane Hydrates and Related Phenomena and Metal Extraction and Bioleaching, together about 29.9% of its articles. (generated from OpenAlex topic counts and CAS ranking data)
Geomicrobiology Journal is a unified vehicle for research and review articles in geomicrobiology and microbial biogeochemistry. Author-generated special issues devoted to specific geomicrobial topics are encouraged. General articles deal with microbial transformations of geologically important minerals and elements, including those that occur in marine and freshwater environments, soils, mineral deposits and rock formations, and the environmental biogeochemical impact of these transformations. In this context, the functions of Bacteria and Archaea, yeasts, filamentous fungi, micro-algae, protists, and their viruses as geochemical agents are examined. Articles may stress the nature of specific geologically important microorganisms and their activities, or the environmental and geological consequences of geomicrobiological activity. The Journal covers an array of topics such as: microbial weathering; microbial roles in the formation and degradation of specific minerals; mineralization of organic matter; petroleum microbiology; subsurface microbiology; biofilm form and function, and other interfacial phenomena of geological importance; biogeochemical cycling of elements; isotopic fractionation; paleomicrobiology. Applied topics such as bioleaching microbiology, geomicrobiological prospecting, and groundwater pollution microbiology are addressed. New methods and techniques applied in geomicrobiological studies are also considered. All submitted manuscripts are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single anonymized and submission is online via ScholarOne Manuscripts. Microbiologists, geologists, ecologists, biogeochemists, soil scientists, limnologists, biological and chemical oceanographers, mineralogists, hydrometallurgists, groundwater specialists, and biotechnologists benefit from research published in Geomicrobiology Journal .
