Regulation of Product Formation in Bacteroides xylanolyticus X5-1 by Interspecies Electron Transfer.

abstract：:Although tractable model organisms are essential to characterize the molecular mechanisms of evolution and adaptation, the ecological relevance of their behavior is not always clear because certain traits are easily lost during long-term laboratory culturing. Here, we demonstrate that despite their long tenure in the ...
