Antibiotic selection of maximal protein production in a Gram-positive bacterium. a B. subtilis TIR libraries expressing gfp were grown on agar plates with different chloramphenicol concentrations. GFP production levels on the different antibiotic concentrations were assayed by exposing agar plates to long-wave UV light. Five individual colonies were randomly picked from these plates and assayed for expression levels assessed by fluorescence per cell density in a microplate reader (b, c)
