ITHACA, N.Y. — Gaining new insight into how efficiently the microbes in large bioreactors produce methane from brewery waste, Cornell scientists hope to use their new knowledge to shape these microbial communities to produce liquid biofuels and ot…
MADISON — Bacteria are among the simplest organisms in nature, but many of them can still talk to each other, using a chemical “language” that is critical to the process of infection. Sending and receiving chemical signals allows bacteria to mind…
Washington, D.C. (September 14, 2010) — A new “on-chip” method for sorting and identifying bacteria has been created by biomedical engineers at Taiwan’s National Cheng Kung University. The technique, developed by Hsien-Chang Chang, a professor at t…
While past research has connected oral malodor to the proliferation of certain bacteria on the tongue, recent research from the Forsyth Institute and the University of Michigan School of Dentistry indicates another group of bacteria is associated with fresh-smelling breath. Investigators used gene sequencing to compare bacteria found on the tongues of individuals with halitosis and those with fresh breath. While not all samples taken from halitosis sufferers had the same bacterial makeup, three particular strains — Streptococcus salivarius, Rothia mucilaginosa and a previously uncharacterized strain of Eubacterium — were the most prevalent species on the tongues of subjects with fresh breath.
