A total of 1496 nt from the 16S rRNA gene were sequenced
as described previously (Go¨tz et al., 2002). The sequence wasreconfirmed using the Thermo Sequenase TM Primer Cycle
Sequencing Kit (Amersham) and the reactions were run
on a LI-COR automatic sequencer (model 4200) using the
LI-COR BASE IMAGEIR software (Science Tec) for analysis.
