Narrator: This is Science Today. While they may lack the
ability to see, hear, smell, taste and touch, most bacteria do have a molecular
signaling system for sensing their environment. Researchers at the Lawrence
Berkeley National Laboratory recently provided the first-ever map of the genes
that determine how a sulfate-eating bacteria interacts with its environment. Staff scientist Aindrila Mukhopadhyay says
they're interested in this bacteria because it is one of the best available
models for examining microbiological impact in environments contaminated with
toxic and radioactive waste.
The primary interest in this organism is that
it is an environmentally important organism, meanwhile not a single one of
these signal transduction systems has been studied. It's almost like studying
an organism without understanding what it hears, what it sees, what it responds
Narrator: This work is an important step for developing future bioremediation applications. For Science Today, I'm Larissa Branin.
