Fig. 3

Germination and growth of P. chrysosporium on the non-fractionated substrate (culture B). The monitoring was performed at 50X magnification. Images show the growth at time 0, 23, 26,29, 46.5, 49.5 and 52 h. The colour change of the square drawn around the colony from red to purple indicates a change in the scale of the image. The sides of the red square measure 9000 μm. The sides of the purple squares are 25,000 μm long, and the image size is 24,576-pixel × 24,576-pixel. The red circles show the position of a single spore over time. At 23 h, the spore was swollen, and a germ tube was formed. At 26 h, a microcolony was obtained where branching start to take place. At 29 h, the amplification of branching continued, and the tips extended, forming bridges with other microcolonies. One colony can be seen at 46.5 h. The red scale bars measure 2000 μm
