A genotype construction platform based on high-throughput flow imaging driven by data has the characteristics of high-throughput, automation, and high sensitivity. By utilizing CRISPR high-throughput genotype construction and droplet microfluidics, ultra high-throughput characterization testing techniques, the relationship between phenotype genes, metabolism, and correlation of HMOs producing strains is deeply explored from the whole genome, such as analyzing the phenotype, genes, metabolism, etc. of HMOs producing strains, and then screening for strains with better expression performance and more stability, achieving efficient strain construction.
