The data-driven genotype construction platform based on high-throughput flow imaging has the characteristics of high throughput, automation, and high sensitivity. By using CRISPR high-throughput genotype construction, droplet microfluidics, and ultra-high-throughput characterization testing technology, the relationship between phenotypic genes, metabolism and correlation of production strains was deeply explored from the whole genome, such as analyzing the phenotype, genes, metabolism, etc. of HMOs production strains, and then screening out strains with better expression performance and more stable strains to achieve the construction of efficient strains.
