Comparison of microbial sensors

Some examples of microbial sensors are given in Table S. 1 [233-241]. Ethanol may be determined using its oxidation by an acetic bacteria of the type Acetobacterxylinum, according to the following reaction  

This oxidation is monitored with a pC 2 electrode whose response diminishes widi ethanol concentration. Cellulose matrices treated with
