He described an expanding body of evidence to show that the composition of the diet directly influences the diversity of the microbes in the gut, providing the link between diet, colonic disease and colon cancer. http://www.physorg.com/news157705943.html Biology Tue, 31 Mar 2009 08:12:57 EST news157705943 (PhysOrg.com) -- Some marine bacteria produce hydrogen sulphide, which is toxic to animals. Scientists have now discovered that bacteria also protect marine animals from this toxic gas. A bacterial bloom detoxified a vast expanse of hydrogen sulphide-containing water off the coast of Namibia, before it could unfold its full deadly impact.
