Chemical communication between bacteria in iron-rich lake aggregates

Abstract: Iron-rich pelagic aggregates have been termed “iron snow” which are different from the more organically rich snow-like aggregates known from marine and freshwater environment. The...

... pelagic aggregates formed in the water column through adsorption of inorganic and organic matter and colonization of motile microorganisms contribute substantially to the energy transfer from the photic zone to deeper water layers. Pelagic aggregates are thus local hot spots for microbial interactions by direct cell contact and feeding, as well as the action of diffusive signals. Chemical signaling molecules have been suspected to regulate bacterial colonization, coordinate group behavior, in addition to antagonistic activities within pelagic aggregates. Comparative metabolomics was be used to identify metabolites produced by microorganisms grown in co-culture by comparison with those of single-strain cultures. In this study, we found Ferrovum sp. (iron oxidizer) was always with Acidiphilium sp.(iron reducer) and that made more difficult to isolate the pure isolate of Ferrovum sp. If Acidiphilium sp. was added to the medium with Ferrovum sp., the growth of Ferrovum sp. would be promoted. Firstly, pure strain of Ferrorvum spp should be purified and isolated with conventional method of streaking plate in artificial pilot-plant water( APPW) medium. After that, supernatant exchange experiment was to detect extracellular chemical mediators produces by the isolates.
