reused in the culture liquid. In these processes, carbon
dioxide gas generated by respiration of the microorganisms is
accumulated in the exhaust gas. When the concentration of
carbon dioxide is over 10%, the growth rate of the
microorganisms and the rate of oxidation are strongly
inhibited. Specification, page 2, line 18, through page 3,
line 1.
4. To prevent the accumulation of carbon dioxide in
conventional processes, the carbon dioxide gas is removed by a
carbon dioxide gas removing means which employs an adsorbent,
such as sodium hydroxide. Specification, page 3, lines 1-3.
5. However, there are problems using such a carbon
dioxide adsorbing system, such as increased production cost
due to acquisition of an adsorption column, an adsorbent, and
the like, and the necessary maintenance thereof.
Specification, page 3, lines 3-7.
