Figure 7

Effect of ammonia and phosphate on growth, pigmentation, sporulation and antibiotic production. S. erythraea NRRL 2338 and S. erythraea Px were cultivated for 7 days on YS agar supplemented with the indicated ammonia and phosphate concentrations (left panels). Antibiotic production in these media was evaluated by microbiological assay using Micrococcus luteus as a tester organism (right panel)
