Fig. 3From: Analysis and description of the stages of Aspergillus fumigatus biofilm formation using scanning electron microscopyExtracellular matrix (ECM) structure of the Aspergillus fumigatus biofilm isolates. Inoculum concentration was 1x106 and at 24 h/37 °C of incubation. The in vitro biofilm was observed by scanning electron microscopy (SEM) and certain types of ECM were differentiated. In the clinical biofilm isolate, a porous ECM (a-b: 1,000X-2,000X; e-f: 1,000X-2,000X) and condensed ECM (c-d: 1,000X-2,000X) was observed. Similarly, the same types of ECM for the soil biofilm isolate were observed. Porous ECM (i-j: 1,000X-2,000X) and condensed ECM (g-h: 1,000X-2,000X; k-l: 1,000X-2,000X).
