Exemplary comparison of semiquantitative FAE gene lineage recovery in Flingern sediments (depth, 6.85 m) retrieved with the FAE-N primer set via different methods: cloning and sequencing (a total of 12 clones) as well as T-RFLP analyses with the different restriction enzymes. Dark gray bars, abundance of FAE gene sequence types affiliated with N47 nmsA; light gray bars, the abundance of those affiliated with OX39 bssA homologues.
