PROCESS FOR PROVIDING A SELECTIVE NUTRIENT MEDIUM FOR FUNGI, ESPECIALLY EDIBLE FUNGI

摘要

Fermented fungus soils have so far been produced in batches by a spontaneous succession of aerobic, thermophilic microflora, especially for growing oyster and Paris mushrooms. The process takes between 2 and 14 days. The novel process is based on the fact that, by separating part of the liquid phase of the fermented medium and the suspended micro-organisms in the liquid phase after or during microbiological reaction, an inoculum is obtained with which can be added to the medium still to be fermented. This partial return of substrate water concentrates micro-organisms, water soluble nutrients and heat in the medium at the start of fermentation and depletes them on the conclusion of fermentation in the medium. The rate of metabolism of the micro-organic population is thus increased and the fermentation time required can be reduced to the extent where the process can be run continuously. USE: The continuous production of selective fungus growing media.
