Viscoelastic behaviour of algae slurries as a function of solids concentration and processing. Data were obtained from shear stress sweeps at 1 rad/s that show the storage (elastic) and loss (viscous) moduli of the slurries of harvested (a), incubated (b) and HPH ruptured (c) Nannochloropsis sp. cells at 12, 20 and 24% solids concentrations. All the slurries were elastic in nature, where the elastic modulus (G, solid squares) was greater than the viscous modulus (G", hollow triangles) at low shear. The crossover between the viscous and elastic moduli, indicated by dashed arrow lines, is often used to characterise the gel-like to fluid-like transition. Duplicate data gave similar results, with a single data set shown for clarity
