Paenibacillus sp isolated by Mette Haubjerg Nicolaisen of University of Copenhagen multiplied and formed a snowflake-like pattern in a semi-solid agar medium. The image was taken by Tomislav Vološen who is a student member of Ákos T. Kovács’s group at the Technical University of Denmark. The group works on the ecology and evolution of Bacilli and closely related genera, including Paenibacilli. They examine bacterial surface colonization, biofilms, secondary metabolites, and interaction of microbes with plants.
