Bacteria can be intimately associated with diatoms. This sea ice Amphiprora diatom cell has bacterial cells attached through an apparently tight association likely via the use extracellular polymeric substances (EPS). SEM micrographs were collected at the UC Riverside Center for Nanoscale Science and Engineering. Samples were filtered, critical point dried to preserve cellular structures, coated with Pt:Pd to prevent charging, and imaged at 2 kv on a Zeiss 1540 FE-SEM.
