In July 2015, Microbial Cell was accepted for inclusion in the selective Directory of Open Access Journals (DOAJ). DOAJ is the reference whitelist for open access journals that meet the high standards in quality and peer-reviewed open access required by this organization. Now, we are proud to announce that Microbial Cell has been awarded the so-called DOAJ Seal, an exclusive mark of certification for open access journals granted by DOAJ to journals that adhere to outstanding best practice and achieve an extra high and clear commitment to open access and high publishing standards. The Seal thus acts as a signal to readers and authors that the journal has an exceptionally high level of publishing standards. You may learn more about the DOAJ Seal here.
