Growth conditions and DNA Isolation
For preparation of genomic DNA, liter cultures of Y412MC10 were grown from a single colony in YTP-2 medium at 37°C in flasks agitated at 200 rpm and collected by centrifugation. The cell concentrate was lysed using a combination of SDS and proteinase K, and genomic DNA was isolated using a phenol/chloroform extraction [43]. The genomic DNA was precipitated, and treated with RNase to remove residual contaminating RNA.
