Study on the submerged fermentation (SMF) of termitomyces eurrhizus

摘要

The influence of KH_2PO_4, peptone and brown sugar on Termitomyces fuliginosu's myceli- um formation was studied with the application of the design of quadratic rotation general combination based on determining the growth curve. A quadratic regression model of biomass to the doses of the above three factors was established. The model fit well and therefore the optimum fermentation condi- tion was obtained. Responses of biomass to the three single factors and to their interactions were dis- cussed. Thus, the highest level of biomass, 21.1 g/L, appeared under the optimized conditions when the initial KH_2PO_4, peptone and brown sugar were 1 g/L, 4 g/L and 72 g/L respectively.
