Core Insights - The article discusses the development of an AI-driven digital cloning selection platform (Digital Colony Picker, DCP) for high-throughput single-cell screening, which addresses the challenges in microbial strain selection and industrial application [2][4]. Group 1: Technology Development - The DCP system utilizes three major technological innovations: micro-chamber separation culture, AI-assisted image recognition, and non-contact laser single-clone picking, enabling precise high-throughput screening of microbial multi-dimensional phenotypes [4][5]. - The DCP platform can independently culture individual microbial cells using a microfluidic chip with thousands of micro-chambers, allowing real-time monitoring of cell growth dynamics, metabolic activity, and morphological characteristics [5][6]. Group 2: Application and Results - In application validation, researchers successfully isolated a "super strain" of Zymomonas mobilis, which showed a 19.6% increase in lactic acid production and a 75.9% improvement in growth rate under 30 g/L lactic acid stress conditions [5]. - The superior phenotype of the isolated strain is linked to mutations and overexpression of the outer membrane transporter gene ZMOp39x027, enhancing lactic acid transmembrane transport capacity [5]. Group 3: Future Prospects - The DCP platform is expected to significantly accelerate the discovery of superior strains, providing strong technical support for metabolic engineering, environmental microbial resource exploration, and industrial strain optimization [5]. - The DCP platform works synergistically with the FlowRACS system, which excels in instantaneous snapshot/sorting capabilities, creating a comprehensive solution for functional strain discovery [6].
