Storage (G’) and loss (G”) moduli of Bacillus subtilis NCIB 3610 biofilms as a function of strain amplitude. These biofilms were grown on 1% LBGM agar plates at 30°C for 24 h and collected via gentle scraping with a microscopy glass slide. (a) Amplitude sweeps at 1 rad s⁻¹ of seven biological replicates. (b) Recovery: amplitude sweeps of a freshly scraped biofilm and a technical replicate of the same sample. Between the measurements, the biofilm was allowed to relax for 5 min.
