Electrochromic polyoxometalate material as a sensor of bacterial activity
Abstract
Lactobacillus fermentum, a bacterium of human microbiota, acts as an electron donor for the electrochromic [P2MoVI18O62]6−. Since the reductive capacity of L. fermentum correlates with its metabolic activity, the reaction with [P2MoVI18O62]6− affords a means of evaluating its activity. Following this logic, we have concluded that vancomycin severely affects the activity of L. fermentum whereas omeprazole does not.
