Fig. 2From: Engineering Escherichia coli biofilm to increase contact surface for shikimate and L-malate productionSelf-assembly of covalent immobilization proteins and nanoparticles based on biofilms. A The schematic diagram of self-assembly of Spy-Tag with GFP-catcher in E. coli MG1655. B The TEM exhibition in different E. coli MG1655. C The SDS-page exhibition in different E. coli MG1655. D Comparing the changes of assembly and no-assembly biofilm, expression and no-expression system by fluorescence detection. E The changes of absorption with or without biofilm. F The schematic diagram of self-assembly of nanoparticles with E. coli. G Comparing the TEM with InP or CdS in E. coli MG1655 biofilm. H, I The confirmation and atom account of randomly chosen biohybrids through XPS analysis. J Detecting concentration of Cd, S, In, and P in different E. coli through ICP-MS. For C, n = 3. Error bars, mean ± s.d. Scale bar for B, G is 1 μm, scale bar for (D) is 5 μm,Back to article page
