- 論文の詳細を見る
Solid state cultures of Aspergillus terreus were carried out at different temperatures using sugar cane trash blended with salts and diluted molasses. A phase of respiration related to spore germination was observed. The effect of temperature on mold growth was evaluated in terms of lag phase, μmax and Xmax values. The germination phase was more sensitive to temperature changes than the apical growth phase. Satisfactory protein content (9-10% dry matter) and protein yield (23% of spent sugars) were observed when the temperature was regulated within a medium range (25-35℃). Preliminary data for scaling-up studies regarding temperature distribution and CO_2 evolution are presented.
