From: Optimization of culture conditions to obtain maximal growth of penicillin-resistant Streptococcus pneumoniae

Figure 4

Growth curves of six strains of PRSP under optimized culture conditions. The high productivity of viable log-phased bacteria demonstrated for S. pneumoniae INS-E611 was reproduced with other 5 strains of PRSP, including diverse serotypes (Table 1). More than 9.0 log10 CFU/mL were obtained in a consistent manner with all strains (curves shown correspond to Tube 7, Phase 2). The variability between strains, evidenced by the time to reach maximal growth, is characteristic of S. pneumoniae.
