Title:
AEROBICALLY CULTURING METHOD BY USING SINTERED METAL FILM
Document Type and Number:
Japanese Patent JP2002191356
Kind Code:
A
Abstract:
To develop an aerobically culturing method by which the feed rate of oxygen can be increased, ammonia can be simultaneously fed, and culturing operation can be carried out without causing the problems of the plugging of a gas-distributing pipe and the mixing of sundry bacteria.
This aerobically culturinq method is characterized in that air, oxygen or a mixed gas thereof are dispersed and fed to a culturing vessel by using a sintered metal film attached to a gas-distributing pipe, and simultaneously ammonia or a mixed gas of the ammonia and air is dispersed and fed to the culturing vessel from a gas-distributing pipe different from the above gas-distributing pipe in the aerobic culture by simultaneously feeding the ammonia and the oxygen.
