DESCRIPTION:Speaker: Dianne Newman\nhosted by Calin Guet\nAbstract: While m
 uch is known about the adolescent phase of bacterial growth\, very little 
 is understood about what sustains bacteria once they reach middle/old age.
   Interestingly\, it is at this later stage that many bacteria begin to p
 roduce colorful\, redox-active pigments—compounds that hitherto have bee
 n classified as “secondary” metabolites\, or “antibiotics”.  A si
 zable fraction of bacteria in the environment are metabolically active\, y
 et slowly growing.  This is true whether they are attached to electrodes 
 in marine sediments\, plant roots\, or surfaces in the human body.  Our r
 esearch suggests that the production of redox-active pigments may actually
  be essential for sustaining life at this late phase of microbial developm
 ent.  This discovery has potentially wide-ranging applications\, from pro
 viding new strategies to boost the efficiency of microbial fuel cells to n
 ew therapeutic targets in the context of infection.\n
