Este protocolo presenta un flujo de trabajo estándar de cribado de alto rendimiento para microorganismos industriales. Consiste en construir una biblioteca mutante mediante mutagénesis ARTP, realizar cribado positivo de gotas con microfluidica automatizada y, posteriormente, verificar los resultados. La fiabilidad del flujo de trabajo se validó mediante el cribado de cepas de B. coagulans de alto rendimiento.
