Figure 4From: Altered lipid composition in Streptococcus pneumoniae cpoA mutants Growth of cpoA mutants in low pH medium. Strains were grown in C-medium, and culture density was monitored by nephelometry [NU]. The growth was examined at pH 8 (circles) and pH 6 (squares). A: R6; B: P104; C: P106; D: R6ΔcpoA.Back to article page
