It has been said that only 1 percent of all bacteria have been classified by species. Soils may be rich sources of new bacterial biodiversity. One such source is the cryptobiotic soils of the desert Southwest. Bacteria were dissociated from soil particles in a blender and grown on R2A agar. Initial findings show that the bacterial population has much diversity based on colony morphology and that populations in excess of 500,000 total cultivatable organisms per g of soil.
