2.2.2.3. Sequence analysis. PCR products (50–100 ng) were purified
using ExoSAP-IT clean up enzyme (USB Corporation, Cleveland, OH,
USA). The purified PCR product was mixed with 9.6 pmol of respective
forward or reverse primers of each microbial group as described in
Section 2.2.2.1 and sent to the Australian Genome Research Facility
(Westmead Millennium Institute, Sydney, Australia) for sequencing.
The sequences of the 5.8S-ITS rDNA region in yeasts and the 16S rDNA
in bacteriawere subjected to online reference data at the GenBank database
using the Basic Local Alignment Search Tool and identified by comparing
sequence homology with available microbial data.
