Those bacterial communities apparently helped motivate researchers to look for something that fed on them.

Those bacterial communities also provide an indication that there's enough life down there to keep the worms fed.

For fermentation to be sustainable at industrial-scale, it is necessary to control the bacterial community inside the fermenter.

The dormant bacterial community of Puna grasses is similar to those found in desert soils.

Distinctive bacterial communities in the rhizoplane of four tropical tree species.

Each of those aphids, in turn, support diverse bacterial communities.

However, process control is much more difficult when working with bacterial communities than when applying enzymatic solutions.

In fact, it looks like the bacterial "community" in the mine may be comprised of a single species.

In response to such changes, the bacterial community evolved with individual members and their specific functions to survive in the oral cavity.

Also, the bacterial community of a colony may change with the seasons.
