摘要： PURPOSE:To provide a mechanical stirring type air-liquid contacting system enabled to obtain a sufficiently high air-liquid contacting efficiency even of non-Newtonian fluids by applying the function of a porous plate type gas stirring tank. CONSTITUTION:In this mechanical stirring type air-liquid contacting system comprising stirring blades 3 attached in a plural number of steps on a stirring shaft 2, the air fed through the blast pipe 5 in the lower part of tank body 1 is finely diffused by the lower ones of said stirrng blades 3, raised by the mixture liquid flow generated by the revolution of said lower stirring blades and discharged outside of system through an air discharge pipe 8. Porous plates 6 each with a short cylinder are fitted between said upper and lower stirring blades 3 and on the upper part of the upper ones of said stirring blades 3 by means of supporting rod 7 or the like. Thereby, rising bubbles are atomized again by said porous plates 6 after or when combined and the ones combined again after passing through said porous plates 6 are atomized by said stirring blades 3 so that air-liquid contact area and mixation stirring efficiency increase.

摘要： PURPOSE: To make the pickup part of a colony transfer apparatus to be reusable, and to obtain an apparatus suitable for the mass culture of single bacterial strain, by applying simple disinfection treatment to the pickup part.
CONSTITUTION: The XY stage 5-1 supporting the culture petri dish 1 and the XY stage 5-2 supporting the test petri dish 2 are placed on a common table 4. A bacterial strain in a designated colony of the colonies in the culture dish 1 is transplanted to the designated position of the medium in the test dish 2 by operating the pickup 6 attached to the transfer means 7. In the above computer- controlled colony transfer apparatus, the transfer means 7 has an arm 7-2 stopped at four concyclic definite positions on the common table and movable vertically at the position. A loop 6-1 is attached to the end of the arm 7-2, and the XY stages 5-1, 5-2, a heating means for disinfection 12 and a cooling means 13 are placed at the four definite positions.

摘要： PURPOSE:A water-containing cellulosic substance and ozone are subjected to gas- solid contact and the remaining ozone is passed through aqueous ammonia, then the resultant cellulosic substance is dipped in the aqueous solution, thus increasing the biodegradability of the titled substance. CONSTITUTION:After a cellulosic substance such as straw, bagasse or used paper is treated with water in the mixing tank 1 to increase the water content, it is subjected to gas-solid contact with the ozone fed from the ozone generator 3 in the ozone- treating tank 2 and sent to the ammonia-treating tank 4 where it is dipped in an aqueous ammonia solution under stirring. At this time, the exhaust gas from the ozone-treating tank 2 is passed through the ammonia-treating tank 4. The cellulosic substance treated with ammonia in the tank 2 is pressed with the press 5 and heated with the heater 6 to remove ammonia.

摘要： PURPOSE:To carry out aerated cultivation efficiently, by carrying out heat exchange from the exhaust gas from a culture tank to liquid oxygen and liquid nitrogen, introducing evaporated oxygen to the culture tank, and solidifying or liquefying carbon dioxide in the exhausted gas so that it is separated and removed. CONSTITUTION:An exhausted gas is taken out from the exhaust pipe 4 attached to the top of the culture tank 1, and introduced through the water removing device 5 to the device for solidifying carbon dioxide or the liquefier 6 of it. Liquid oxygen or liquid nitrogen produced by the oxygen production unit 2 of the low-temperature separating type is fed through the line 7 to the device for solidifying carbon dioxide or the liquifier 6 of it, where heat exchange takes place, solidified or liquefied carbon dioxide in the exhaust gas is exhausted from the line 12 to the outside of the system. While evaporated oxygen is sent from the feed pipe 11 and forced to flow together with the exhaust gas with carbon dioxide removed, and introduced to the culture tank 1.
