Amperometric biosensors for detection of phenol using chemically modified electrodes containing immobilized bacteria

Popis výsledku v původním jazyce

Eight strains of Pseudomonas were studied for development of phenol sensor. The immobilization of cells was performed by absorbing them on the working part of mediator-modified screen-printed electrodes (SPEs). Only three Pseudomonas strains were able totransfer electrons resulting from specific oxidation of phenol to the electrode by means of mediators; ferrocene, duroquinone and dimethyferrocene were successfully used with the strains 394 (p20), 74-III and 83-IV (working names), respectively. The lower limits for detection of phenol were 1 muM for the strain 74-III and 10 muM for the strain 83-IV and 394 (p20). Calibrations were obtained as the dependencies of logarithm of current changes (log DeltaI) on logarithm of concentration (log C), log DeltaI vs. log C. Among all substrates tested (phenol, catechol, hydroquinone, ethanol, methanol, propanol, isopropanol, isobutanol, isoamylalcohol, acetate, glucose, xylose, vanillin, 2,4,6-trichlorphenol, 2,3,6-trichlorphenol, 4-hydroxy-3-me
