Elevated bacterial abundance and exopolymers in saline frost flowers and implications for atmospheric chemistry and microbial dispersal
Frost flowers (FF) have been studied for their potential influence on ice-surface reflectivity and roles in atmospheric chemistry, but not as microbial habitats. We examined FF grown in a freezer laboratory from a bacteria-containing saline solution and FF formed naturally in the coastal (April) and...

Frost flowers (FF) have been studied for their potential influence on ice-surface reflectivity and roles in atmospheric chemistry, but not as microbial habitats.
