Biofilm formation of P. stutzeri A1501 in different media. (a) Biofilm biomass of A1501 was determined by CV biofilm assay after 2-day growth with A15, KLN or LD medium, respectively, in 96-well microtiter dish. Shown under each column was a representative well post CV staining. (b) Biofilm formation of P. stutzeri A1501 grown in minimal KLN−, KLN+ and rich LD media in the microtiter dishes during a week of growth. (c) The OD₆₀₀ of bacteria grown in the corresponding wells for the biofilm assay shown in the graph b.
