Popis: We have studied the microbial attack on wheat straw that occurs during the process of composting for growth substrate production for the edible mushroomAgaricus bisporus. Both transmission (TEM) and scanning (SEM) electron microscopy have been used. Samples were taken at all stages of the composting process. They show an ecological succession of microbial attack initially consisting of a predominantly bacterial flora with only few fungi present. Very few microorganisms are present on the surface of dry straw as the starting material. If stable litter (horse manure/wet straw) is used as a starting material, dense bacterial populations are already present. Bacterial numbers increase very rapidly in the initial stages of composting, and then decline, but with an increase in the proportion of spore forms.
