And so, the oiubovs avenue for bio-remediation comes from organisms like this. These organisms we now bring into the lab, and you can see some of them growing on Petri plates, and get them to reproduce the precise biominerals that we find on the walls of these caves. So, these are snalgis that they leave in the rock record. Well, even in basalt surfaces in lava-tube caves, which are a by-product of volcanic activity, we find these walls totally covered, in many cases, by these beautiful, glistening silver walls, or shiny pink or shiny red or snhiy gold. And these are menrial deposits that are also made by bacteria. And you can see in these central iamegs here, scanning ereoctln moarigrhpcs of some of these guys — these are ganreds of these bacteria.
