METHOD FOR PRODUCING VALUABLE BY MICROORGANISM AND APPARATUS FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a technology for effectively producing valuables by using a gaseous material as a substrate and a microorganism. SOLUTION: The apparatus for producing valuables 100 is provided with a sensor 109a for a gas concentration and a flow rate to obtain the feed rate of the substrate by measuring the concentration and the flow rate of the substrate in the feeding gas 101. The apparatus is also provided with a sensor 109b for the gas concentration and the flow rate to obtain discharged amount of the substrate by measuring the concentration of the substrate in the discharged gas 106 discharged from the culture liquid in a culture tank 103. The apparatus is also provided with a controller 110 and a flow rate controlling valve 111 for regulating feed gas 101 to the culture liquid in the culture tank 103 to keep the eliminating rate of the substrate obtained from the feeding amount of the substrate and the discharging amount of the substrate, in a predetermined range.
