| Outline of Final Research Achievements |
In this study, we aimed to develop a microfluidic droplet-based whole genome amplification method for single bacterial cells. We developed a microfluidic device for generation of picoliter-sized droplet for compartmentalized reaction environment. Single bacterial cells or their genome DNA fragments were encapsulated into each droplet. By compartmenting genome fragments into individual droplets, DNA fragments are amplified uniformly, that minimizes amplification bias and the effect of contaminating DNA. Our results demonstrated the potential of microfluidic generated droplets as an efficient tool for the analysis of single cell genome along with great reduction in the cost and labor investment required for the investigation of genome diversity of uncultivable bacteria.
