Microscopic image of biofilm on rock in BioRock experiment

Fluorescence microscopy image of biofilm of Spingomonas desiccabilis growing over and into the surface of a basalt slide as part of BioRock experiment. Organisms are stained with DNA binding sye Sybr Gold. Growth can be seen into the rock cavities. (Image Courtesy of ESA)

jsc2019e039825 (7/16/2019) --- Preflight Ffuorescence microscopy image of biofilm of Spingomonas desiccabilis growing over and into the surface of a basalt slide as part of BioRock experiment. Organisms are stained with DNA binding sye Sybr Gold. Growth can be seen into the rock cavities. The purpose of the Biorock investigation is to examine the effects of altered gravity on the rock/microbe/liquid system as a whole. (Image Courtesy of: ESA)
