Beyond research funded at academic institutions and national laboratories, DOE BER supports two facilities that conduct microbiology research. The DOE Biological and Environmental Research (BER) program supports scientific research and facilities that seek to understand complex biological, earth, and environmental systems.

The Department of Energy (DOE) supports microbiology research that helps us maintain energy security and a sustainable environment. No known viruses are capable of reproducing themselves-they need cells from other organisms so they can copy themselves.ĭOE Office of Science: Contributions to Microbiology Research Not all biologists consider viruses to be living organisms.

Viruses are noncellular entities that consist of a core of DNA or RNA surrounded by protein.

Their cells have nuclei, and many fungi are multicellular.

Fungi include mushrooms, molds, and yeasts.

Algae are unicellular or multicellular organisms that have nuclei and that obtain energy through photosynthesis, similar to plants.

They are found in wide range of environments where some can eat bacteria to survive. They obtain food by surrounding it with their cell membranes.

Protozoa are unicellular microorganisms that have nuclei.

This gives them the ability to live in extreme environmental conditions.

Archaea are like bacteria, but they have different structures and properties.Bacteria are single celled microbes that lack a nucleus.They include bacteria, archaea, fungi, protozoa, algae, and viruses. Microorganisms can be unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). We can also use microorganisms to help us produce life-saving drugs, manufacture biofuels, clean up pollution, and grow crops. Microorganisms affect our climate, determine how food spoils, and both cause and control diseases. For instance, they are responsible for how biological materials break down and decay. These tiny organisms shape how nutrients move through the environment, controlling how ecosystems work. Microorganisms (also known as microbes) are essential to life on Earth complex organisms (including human beings) would find it nearly impossible to survive without them. Microbiology is the study of microorganisms that are usually too small to be visible with the human eye without a microscope.
