Identification In 1998, William Whitman and his team at the University of Georgia estimated the number of bacteria living on the earth by examining different habitat types and estimating those numbers separately. read more

In order to estimate the total number of bacteria on Earth, the group at Georgia divided the Earth into several areas, including oceanic and other aquatic environments, the soil, the subsurface of soil, and other habitats such as the air, inside animals and on the surface of leaves. The study brought some surprises. read more

Now, for the first time, a team of researchers from the University of Georgia has made a direct estimate of the total number of bacteria on Earth -- and the number makes the globe's human population look downright puny. read more

Bacteria are the huddled masses of the microbial world, performing tasks that include everything from causing disease to fixing nitrogen in the soil. Now, for the first time, a team of researchers from the University of Georgia has made a direct estimate of the total number of bacteria on Earth and the number makes the globe's human population look downright puny. read more
