The Integration of Focused Ultrasonication, ddPCR, and Flow Cytometry Effectively Estimates Genome Copies per Cell and Enhances DNA Extraction Efficiency in <i>Escherichia coli</i> Samples

, for various DNA-based techniques, including metagenomic analysis of complex microbial communities and the development of new DNA extraction protocols. This novel protocol addresses a longstanding limitation in microbiological research and has the potential to significantly enhance accuracy and reproducibility across various applications. While there is significant potential for applying this approach, the authors acknowledge that further studies using microorganisms with thicker cell walls will enhance the utility of this framework. However, the knowledge generated in this study can be readily applied and tailored to the specific objectives of individual research groups.
