Fig. 4From: Flexible material formulations for 3D printing of ordered porous beds with applications in bioprocess engineeringa SEM of MAETAC monomers revealing bacterial biofilm adhered onto 3D printed support after 3Â days of incubation with R. opacus culture in exponential growth phase. BT is desulphurized by R. opacus into phenolic end products, as detected using Gibbs test on perfusate samples visualized by blue colour (b) and measured at 610Â nm (c)Back to article page
