Fig. 2From: Deletion of Rap-phosphatases for quorum sensing control in Bacillus and its effect on surfactin productionBar charts of promoter activity PsrfA-lacZ (a), surfactin concentration (b) and ComX activity (c) over the course of cultivation until the maximum surfactin concentration of reference strain KM1016 was reached at t = 16 h. LOQ = 42.7 MU for ComX bioassay, as determined in Treinen et al. (2021)Back to article page
