Aerobic fermentation with porous solid media such as brans and sawdust-molasses medium can be conducted efficiently by high-heap aeration process using an incubator furnished with cooling device in its interior.In the present investigation, citric acid fermentation in sawdust-molasses medium was dealt with using incubators furnished with water-cooling pipes.Outline plans of pilot plant incubators, conditions of operation, preliminary tests concerning various additions known as stimulants for citric acid formation and time courses of respiratory as well as acid-forming activity are presented.The heat of metabolism was coputed on the basis of respiratory activities on the one hand, and from the measured temperatures and the flow rates of air and of cooling water, on the other.Under adequately controlled condition, citric acid accumulation attained to about 50% of sugar in blackstrap molasses within 4 days.The results concerning espercially the unevenness of a culture heap in an incubator, heat transfer in the interior of an incubator are discussed.
