Electrochemical detection of microbial stress

Patent ·
OSTI ID:2293988
; ; ; ;
The present invention is directed to a method of detecting microbial stress. The method comprises the following: providing an electrochemical device having at least one reference electrode and one working electrode wherein the electrochemical device also contains a fermenting microbe, setting an electrochemical potential, providing a source of electrical energy electrically connected to the at least one working electrode, detecting a transfer of electrons from the working electrode to the fermenting microbe, wherein the detection is an indication of microbial stress, and providing a remedial action in response to the indication of microbial stress.
