Glucose utilization is slow and low count ratio of streptomycin is produced during this phase. The medium pH also rises from 6.7 or 6.8 to 7.5 or higher. The next phase is the streptomycin producing phase which ranges from 24 h to 6-7 days. Rapid utilization of ammonia and glucose occurs and substantial production of streptomycin is observed.

The reduction in spore production is significantly negatively correlated with antibiotic production (F 1,29 = 26.58, r 2 = 0.478, P < 0.001) (fig. S5A). This provides evidence that antibiotic production is costly to S. coelicolor and that there is a direct trade-off between antibiotic production and reproductive capacity, possibly because ...
