Phenols or phenolics are a large group of compounds of natural
and anthropogenic origin [1]. The indiscriminate release of wastes
generated during dyes, chemicals, textiles, resins, and plastics
production, as well as during the processes of wood preservation,
and petroleum refining causes phenolic compounds pollution [1].
Since phenolics are persistent in the environment and highly toxic
[1], they are included in the EPA list of priority pollutants [2]. EPA
sets the maximum concentration limit of phenol in water for the
protection of public health at 3.5 mg L1 [3], while in the European
Community the maximum admissible concentration of phenolic
compounds in drinking water is 0.5 mg L1 for the total content and
0.1 mg L1 for the individual content [4]. The maximum levels of
phenolics in surface water for drinking purposes should be in the
1-10 mg L1 range, depending on how it is treated [5]. Hence, a
number of high sensitive chromatographic methods were suggested
for phenolic compounds determination [6,7]. Nevertheless,
they are not well suited for in situ analysis. Therefore, recent trends
in analytical chemistry rely on the use of biosensors as an
alternative to the above mentioned traditional techniques. Several
biosensors were developed for phenolic compound determination
