Fig. 2From: Engineering of Streptomyces lividans for heterologous expression of secondary metabolite gene clustersEffect of clusters deletion on fitness and growth parameters. a Growth curve analysis of the wild type S. lividans TK24 (blue) and the mutants S. lividans ΔYA9 (red) and S. lividans ΔYA11 (green) grown for 6 days in DNPM media. Samples were taken every 24 h and the wet biomass was measured. b Phenotype of the S. lividans TK24, S. lividans ΔYA9, and S. lividans ΔYA11 after 6 days growth on MS mediaBack to article page
