From: Development of a novel heterologous β-lactam-specific whole-cell biosensor in Bacillus subtilis
Disk diffusion assay conducted with different Streptomyces isolates and the Biosensor 2 in ΔpenP. The two Streptomyces isolates #7 and #8 represent an example from the collection of yet unidentified Streptomyces soil isolates. A disk soaked in cefoperazone (CFP, 200 μg/ml) and Penicillium chrysogenum (Pchr) served as positive controls. This result demonstrates the applicability of the biosensor in the screen for novel active compounds belonging to the β-lactam family. To view the full dataset, see Supplement 1, Figure S13. Representative images of triplicates are shown
