Molecular identification
Bacterial DNA was extracted manually by boiling a loop full of
culture in sterilized distilled water and centrifugation at 13, 000 rpm
for 10 min. The supernatant containing the extracted DNA was
used to amplify 16S ribosomal DNA segments by PCR (Bio-Rad i
cycler) using 16S-27F and 16S-1492R. Bioline, Biotaq
TM DNA
Polymerase kit and dNTPs set was used. DNA was visualised at 80
V and 400 mA for 35 min on agarose gel (0.8% (w/v) in TAE buffer
1x, 0.1 µl Ethidium Bromide solution).
