Microbial Biosystems is an open-access, non-profit, and peer-reviewed journal that publishes original papers in all aspects of microbial biology by the Arab Society for Fungal Conservation. MBJ was founded and owned by the Arab Society for Fungal Conservation in 2016. MBJ is a biannual journal till the end of 2025. In 2026 it will be quarterly published. The journal is open to papers dealing with all aspects of Microbial biology, systematics, and ecology. Research studies containing novel and significant findings, from the molecular level to ecosystems are welcome.

MBJ has been conceived in consideration of the recent progress in microbial research. An editorial board has been devised to ensure that all the main trends of contemporary microbial biology science are represented. Manuscripts are classified as 'Full Paper', 'Rapid Report', or 'Short Communication'. A Rapid Report is intended for publication, in a concise form, of new and relevant findings. The classification as Rapid Report is determined by the Editor in Chief. A Short Communication (no more than two printed pages) is for a concise but independent report. It is not intended for the publication of preliminary results. Review articles are also published, but only upon invitation by the Editor. An international panel of highly qualified referees warrants the highest scientific standard.
