16S rDNA sequence analysis
Total genomic DNA was extracted from the isolated microorganism using the benzyl chloride method [7]. The purified DNA was used as the template for amplification of the full-length 16S rDNA using bacterial specific primers BSF8/20 (5’agagtttgatcctggctcag 3’) and REVB (5’ ggttaccttgttacgactt 3’) with DyNAzyme EXT DNA polymerase (Finnzyme, Espoo, Finland), according to Kanokratana et al. [8]. The PCR products were gel-purified using a QIAGEN Gel Extraction kit, ligated to pTZ57R/T vector (Fermentas, Vilnius, Lithuania) and transformed into Escherichia coli '+ĮEWKHKHDW-shock method. Transformants were selected on Luria-Bertani agar plates containing ampicillin (100 μg/ml), supplemented with 40 μg/ml 5-bromo-4-chloro-3-indolyl-ȕ-d-galactopyranoside (X-GAL) and 20 μg/ml isopropyl-ȕ-d-thiogalactopyranoside (IPTG). Sequences were initially compared to the available databases using the BLAST network services to determine the approximate phylogeny.
