<p>PURPOSE:A gaseous substrate is brought into direct contact with an immobilized microorganism to effect the direct synthesis of an objective compound in a practical scale. CONSTITUTION:The objective product is formed, as a gaseous substrate is directly fed to the immobilized microorganism. In order to carry out the process according the present invention, for example, an immobilized microorganism is placed in the reactor 1 and the liquid containing nutrients such as nitrogen source, minerals and others is jetted from the nozzle 4 by the operation of the valve 6 or dripped or allowed to flow down to the carrier containing the immobilized microorganism. And, as the nutrient solution is dropped, a substrate gas of an appropriate nutrient composition is fed from the pipe 5 through valve 6 into the reactor 1 to bring the nutrient solution into contact with the microorganism immobilized on the carrier whereby the objective product is obtained. The objective substance formed is collected through the gas outlet 7 in a gas tank 10. The suitable microorganism is a methane-producing bacterium utilizing carbon dioxide, hydrogen gas as substrates.</p> |
