Abstract
In addition to their well-known general toxicity, mycotoxins have also
been found to often exert genotoxicity. In turn, not only the presence of
the mycotoxins is required to be determined, but such DNA-damaging
effects by these substances are also needed to be detected in routine
monitoring of mycotoxin. The main purpose of this article is to demonstrate the utility of a
proposed special fiber optical SOS-chromotest type biosensor, based on the SOS-lux assay in
recombinant Escherichia coli cells, in rapid measurement of the genotoxicity level of
mycotoxins. The optrode-based fiber optic biosensor and its main operating conditions for
such express analysis have been worked out, moreover, its efficacy in the determination of
the effects of certain investigated mycotoxins e.g.,T2 mycotoxin, patulin, aflatoxin B2,
zearalenone and ochratoxin on the genetic apparatus applied and their activation of the
operon of the reparative genes is reported. The genotoxicity of the mycotoxins studied fell in
the order: T2 mycotoxin > aflatoxin B2 > patulin >> ochratoxin > zearalenone.
