Fascinating. Reinforces the value of bacteria.

Just Science

Bacteria do not have taste buds or eyes. However, they have very fine-tuned senses that relay information about the status inside as well as in their environment. To compete and survive in virtually all environments on the planet, bacteria have evolved to sense and utilize many chemical compounds (most of which are still unknown) for energy and existence no matter how we as humans feel about these compounds. Even toxic compounds are easily metabolized by some bacteria. Whether it is hydrocarbons like petroleum or groundwater contaminated with dry cleaning chemicals, bacteria have evolved pathways to utilize these compounds.

Imagine restoring highly contaminated land for public use without expensive machinery or excessive human exposure. Current research within DOE is working towards this goal through bioremediation, utilizing bacteria with ability to render radioactive or otherwise hazardous material harmless. Even though most microbes presently performing this task are unknown, meta-sequencing projects are…
