摘要

以固態醱酵改進農業資源的利用方法時，需要研究基質之初水分、最大容許量、水活性、微生物之附著力，同時，描述這些因數時也需注意接種密度、微生物量、微生物之微氧性、質量及熱能之運輸。本研究室曾從事許多農業資源之固態醱酵及中級水分食品之研究，因而得到以下的結論：因質量及熱能之運輸太慢，使得微氧性微生物之數目及活性增加，所以我們可以最適合生物反應槽設計之立場進行樹皮堆肥、菌種製造及高梁酒釀造，又探討兼性厭氧性微生物對高梁酒香味之影響；上述指標亦可應用在其他場合，例如廢水中難分解之暗色有機物去除及容易生物分解的塑膠之開發等。

To improve processing of agricultural products (such as wheat, sorghum and compost) through solid state fermentation (SSF), the effects of initial moisture, water holding capacity, water activity, and microbial adhesion capacity of substrate on the performance of the operation need to be investigated. The appropriate variables for the description of these effects including inoculum density, microbial mass, microaerophily and heat and mass transfer rates have been studied in our laboratory. Several conclusions are drawn for SSF of agricultural products and on intermediate traditional foods Low heat and mass transfer rates result in an environment which is favorable to microaerophiles and thermophiles. The optimun design of an SSF reactor applied to bark waste composting, spawn making, and sorghum brewing is presented. The effect of facultative anaerobes on sorghum-liquor aroma is also discussed. Finally, biosolvent recovery of resistant organic polymers in waste water and the construction of biodegradable plastics are considered as examples in which the above studied variables involved in SSF are applied to new systems.
