Bacteria are nature’s recyclers. They have the ability to degrade an astonishing number of compounds, due to their evolution in myriad locations over millions of years, enhancing their suitability for a large variety of natural and manmade systems. Once the environmental and nutritional requirements of different species of bacteria are quantified, their abilities to completely clean and re-stabilize a system can be harnessed. Certain challenge and selection techniques, such as those used in the production of Clear-Flo® formulas ,can be employed to further enhance their appetites for certain difficult to degrade compounds.
