A wash with mild non-ionic detergent
TritonX-100 (0.1% v/v) removes any remaining fat and hydrophobic
protein. Two subsequent SNW washes (8000 rpm 10 min) were
performed to get rid of any trace EDTA or TritonX-100. After processing,
the bacterial pellet was denatured in 25 ml of SNW at 95 C
for 5 min, centrifuged at 8000 rpm for 5 min. The DNA present in
the supernatant was used as a template for PCR.
