Colony PCR has been found to be a useful technique applicable to both gram-negative and gram-positive bacteria.[5,7] Satisfactory PCR products were obtained while using this method with intact cells, colonies from agar plates, and even liquid cultures which were stored at 4°C for up to 3 months. Moreover, this method has also been used to identify target genes or to distinguish homologous recombination events from nonhomologous ones in yeast.[4] Performing DNA extraction is not recommended for PCR purposes when there are few bacterial cells in the sample because DNA loss is inevitable in the process, which would hinder subsequent PCR amplification.
