It was a very minimal media, if something's growing on there, you know it's able to fix carbon and nitrogen out of the atmosphere, or using one of the specifically chosen carbon and nitrogen compounds we add to the media. Either way, these organisms are very efficient recyclers of organic material.

These are incredibly diverse microbial communities with hundreds of different organisms, if you were counting animals in the Amazon, you wouldn't come close to the diversity of these biological soil crusts.

We're trying to find examples of the most extreme environments we can on Earth, we're trying to get into places where biology runs headlong into the inorganic part of the Earth, where any nutrient you want to pick up you've got to get from a rock or the atmosphere.

The interesting thing is that the Bacillus sends out these little shuttles to hopefully get ahold of iron and bring it back, but there is no guarantee.
