FIG. 1.
Photos of a stable, mucoid P. aeruginosa NH57388A colonies after serial subculture on BAP (a), a stationary-shaken ox broth flask culture of nonmucoid P. aeruginosa NH57388B after 2 weeks (b), alcohol precipitation of alginate (white arrow) from stationary-shaken ox broth flask cultures (30 h) of mucoid P. aeruginosa NH57388A (left) and nonmucoid NH57388B (right) (d), and mucoid P. aeruginosa NH57388A after 14 days stationary-shaken (left) or static (right) aerobic culture in a tube (c). Three phenotypes are indicated by the black arrows in panel c: M, mucoid; NM, nonmucoid; and SCV.
