Title: Two Types of Models on Solid State Fermentation Involved in Mushroom Cultivation for Prediction of Biomass Formation
Author: Hsi-Hua Wang
Commercial mushroom cultivation includes three processes of solid state fermentation, composting, spawn making and cultivation itself (figs. 1 and 2), in which all the substrates are not in the submerged state but in the state of moist solid (Wang and Chiou, 1977). the texture of the substrates determines the porosity and water holding capacity of the substrate, and also affects the thermodiffusibility (Wang et al., 168 and Finger et al., 1976). The porosity limits O2 supply for microbial growth. The moisture of the substrates is much less than those of the microbes concerned (Table 1). Thus, the water supply from the substrates is a limiting factor for biomass formation. In addition, both the microbes and the substrates in solid state do not move but the microbes make colonies on and in static substrates. Therefore, one may consider the texture of substrates in connection with water supply, O2 supply, thermodiffusibility, the frequency of growth initiation in substrate, the effect of gases or accumulated products and microbial and/or nuclear selection as the parameters to determine the processes, as suggested in Kaoliang brandy brewing and mushroom cultivation (Wang et al., 1974; Ma et al., 1976 and Wang et al., 1975).Please login to download the PDF for this proceeding.
