The growth of the Lentinus edodus mycelium in a solid nutreint medium was investigated at using the solid fermentation ( SSF) process. This process ran in a prototypie bioreactor used for the growth intensification of higher fungi mycelia. It has been found that the strongest effect on the mycelium growth exerted humidity of the nutrient medium and size of the flowing air stream.
The reconstitutional properties of mushroom fruitbodies dried convectionally and sublimatically were analysed. The fruitbodies of nameko (Pholiota nameko) and shiitake (Lentinus edodes) which differ in the structure, chemical composition and growth rate were examined. It was found that the most important influence on the rehydration rapidity (time of rehydration) was exterted by the method of drying. The differences between these two species of mushrooms were also distinctive and dependent on individual features of raw substrate and was closely connected with the examinated mushroom species.
