Fig. 1

Scanning electron microscopic photograph of raw FSF matrix (a), smooth fibre in the raw FSF (b), partially fractured FSF after 36 h in the mesophilic digester (c), step-by-step magnified sample from the mesophilic digester after 24 h digestion (d–f), bacterial clusters within the digested FSF matrix sampled from the thermophilic digester after 48 h digestion (g–i). The areas in red rectangles (d, g) represent the zoom-in areas of the subsequent figures (e, h), respectively. The areas in yellow rectangles (f, i) were the scanning location for the EDX analysis (results shown in Additional file 1: Table S1)
