This product integrates the function of Raman fingerprint detection and automatic clone selection of colonies. It can perform image recognition, Raman detection, data analysis and species identification of colonies in situ in the petri dish, and automatically pick the target strain into the porous plate for expanded culture. It can avoid the waste of time and labor cost caused by large-scale sequencing identification, effectively improve the efficiency of strain screening, and provide a powerful tool for engineering bacteria screening and microbial resource library construction.
