2.4. Characterization and molecular taxonomy
The selected isolates were subcultured on YPS fermentation
medium for 24 h at 30
C. 1500mL were transferred into micro
centrifuge tubes and the cells were recovered by centrifugation at
10,000g for 2 min. The supernatant was discarded and the DNA
extraction was realized following the methodology proposed by
Yamada et al.[16]. The D1/D2 domain of 26S rDNA region was
amplified using the primers NL1 (5
