Clones showing the same band positions in the gel
indicate the same melting behaviour. They were pooled
to one group because of possible same sequence. Clones
that show different migration behaviour in the gel, were
sequenced and phylogenetically classified (Kuffner et al.,
2004; Schabereitner-Gurtner et al., 2001). The length of
the clone inserts were 601–642 bp for the eubacteria and
370–374 bp for enterobacteriaceae.
