Fig. 4From: Type IIs restriction based combinatory modulation technique for metabolic pathway optimizationβ-carotene yield and cell mass of representative strains from the combinatory expression library DXS37-IDI46 (pACYC184-AL-mva). Strains include ALV104, ALV131, ALV100, ALV108, ALV20, ALV63, ALV25, ALV133, ALV23, ALV145 and parent strain DXS37-IDI46. Three repeats were performed for each strain, and the error bars represented standard deviationBack to article page
