Caulobacter crescentus is the most common nonpathogenic (does
not cause disease) bacterium in nutrient-poor freshwater streams. In the swarmer
phase of its three-phase life cycle, C. crescentus is motile and chemically
sensitive, characteristics that help it locate nutrient sources. In its nonswarmer
phase, it adheres to solid substrates such as rocks. Microbial Genome Program
(MGP) scientists are determining the DNA sequence of the genome of C. crescentus,
one of the organisms responsible for sewage treatment. The organism may then
be modified for use as a bioremediation agent to remove heavy metals from wastewater
streams. The MGP funds studies on microorganisms having potential for cleaning
up toxic waste such as metals and chemicals from soil and groundwater contaminated
during four decades of nuclear weapons production.
