Fig. 1From: Construction of cellulose-utilizing Escherichia coli based on a secretable cellulaseCell density, accumulation of extracellular proteins and Cel-CD activity during cultivation. Cells were cultured in LB medium at 37 °C. Circle markers totally extracellular proteins in the culture medium; triangle markers growth curve of the Cel-CD expression strain; square markers the endo-glucanase activity of Cel-CD in the culture mediumBack to article page
