Fig. 2.

A representative CO₂ profile of a fungal solid state reactor experiment after correcting for dilution. The lower line represents respiratory CO₂ as indicated by the interpolated dashed line and the upper line is the sum of respiratory and oxidized VOC CO₂ as represented by the interpolated dotted line. Values switch between respiratory CO₂ and CO₂ from both fungal metabolism and VOCs every 3 h. The graph is split into growth phases based on the shape of the respiratory CO₂ curve
