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 condition was obtained. Responses of biomass to the three single factors and to their interactions were discussed. 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.展开更多

Research into the character of the mode of action of these substances on various living systems is necessary to elucidate the possible unfavorable biological consequences and improve measures on their ecological safety. In this work, the effect of acridone-N-acetic acid on mushroom mycelial growth was tested and the culture of basidiomycete Lentinula edocles （shiitake） has been used. The influence of acridone additive upon the fungal mycelium growth on liquid （submerged） and agar media was examined within the wide concentration range of acridone carboxy-derivative. The results obtained testify to the relative ecological safety of these substances for mushroom organism, and to the mycelial growth promoting capability of acridone-N-acetic acid at favorable concentrations, both under the solid-phase and liquid-phase culture conditions. In fact, the very first step toward the investigation into the systems ＂macromycete-acridone series compound＂ has been made.展开更多
