Fig. 4: Mechanical properties for microbial biomass (MB) based materials and other engineered or natural materials.
From: High oxygen barrier packaging materials from protein-rich single-celled organisms
a Tensile stress-strain curves for the MB-based film (black line) and tray (red line), plasticized with 25 wt% and 20 wt% glycerol respectively. b Young’s modulus, (c) maximum tensile stress and (d) strain-at-break. Average and standard error calculated from n = 3 (film) and n = 7 (tray). e Two Ashby plots, showing stiffness versus tensile strength properties for different engineering materials and natural materials, including the MB-based materials (yellow dots). Drawn after D. U. Shah2.
