Microbes at work cleaning up the environment

It may sound counterintuitive to use a microbial protein to improve water quality. But some bacteria are doing just that to protect themselves from potentially toxic nanoparticles in their own environments, and clean up crews of the future could potentially do the same thing on a larger scale. ...

In nature, proteins sweep up nanoparticles

...aggregates, which are produced as a consequence of microbial activity, actually contain a lot of protein,” says Banfield. “This is very interesting because biomineralization has traditionally been thought of as a phenomenon that occurs within a cell, or in contact with it. But in this case, we see an intimate ...

...f it gets the opportunity, it hits its host with a microbial sledgehammer. It then eats the remains and lays low until the next host comes along." The genome sequence is peppered with genes that produce enzymes to digest proteins and other animal material in the soil. Also found, uniquely in this species, i...
