All theoretical HaeIII-HhaI T-RFs of sequenced clones were found in community T-RFLP profiles. The only exception
was a theoretical T-RF size of 132 bp that was not detected in the T-RFLP analysis. Several sequences showed identical
T-RF sizes (Table 4). A relationship between phylogeny and location in soil was found. Some bacterial groups such as the
Holophaga/Acidobacterium division and most Prosthecobacter members were mainly present in smaller size fractions (silt and clay), whereas Proteobacteria were evenly distributed in all ractions (Table 4).
