Fig. 4.

Adhesion of IBB477 and its deletion mutants in putative adhesion genes to a bare polystyrene (PS), b mucin-coated polystyrene (PS + PGM) and c fibronectin-coated polystyrene (PS + FN). Adhesion is expressed as optical density (OD_583nm) of stained cells. Means ± standard deviations from three independent experiments are shown. The p values were calculated using Welch t test (**** p value < e⁻⁴). Δbig + pGhost9big-complemented Δbig mutant (containing pGhost9 with a gene encoding the AJ89_07570 protein)
