From: Constitutive and regulated expression vectors to construct polyphosphate deficient bacteria
Biofilm formation assays in regulated polyP-deficient Pseudomonas sp . B4 cells. (A) Crystal Violet stained PVC plates of polyP-deficient Pseudomonas sp. B4 cells under repressed (Glucose 1%) and induced (Arabinose 0,5%,) conditions. (B) Quantification of crystal violet dye attached to the cells forming biofilms on PVC plates. Error bars are the average of two determinations in four biological replicates.
