Slow and steady! After 15 years of continuous cultivation, we finally isolated the first psychrotolerant ammonia-oxidizing archaeon (AOA) from an arctic environment, Ca. Nitrosocosmicus articus! Our new article in Frontiers in Microbiology: doi.org/10.3389/fmic...
Our Review Article is online! We are happy to share our summary about molecular and cellular biological discoveries in archaea that have long foreshadowed a close relationship to eukaryotes, which is now so well manifested in the Asgard archaea. link.springer.com/article/10.1...
