This invention relates to a method for producing microbial cells by culturing and collecting them.
従来、炭酸ガスを炭素源として利用可能μ微生物を培養
して微生物菌体を回収せんとする場合、水素f、[B菌
が0゛利であると云われている。Conventionally, when attempting to culture μ microorganisms that can use carbon dioxide gas as a carbon source and recover microbial cells, it is said that hydrogen f, [B bacteria have an advantage of 0.
その理由は、原料中に不純物がなくクリーンであるため
、微生物菌体を飼料としてFll用する際、η性の問題
が少ないこと、水素細菌の増殖速度が独立栄な細菌の中
で、特に速いことなどが挙げられる。The reason for this is that the raw materials are clean with no impurities, so there are fewer problems with η when using microbial cells as feed, and the growth rate of hydrogen bacteria is particularly fast compared to other independent bacteria. There are many things that can be mentioned.

、窒素ガスを唯一の窒素源として生育することに着目し
、本発明を完成させたものである。[Example] A means to solve the problem, the present inventors first discovered that Xanthobacter belongs to the genus Xantobacter.
After providing a method for producing 611 hydrogen bacteria that can grow under high-oxygen conditions (Special Publication No. 5951995), as a result of further research into the effective use of the created microorganisms, we found that nitrogen gas was used as the only nitrogen source. The present invention was completed by focusing on the growth of plants.

−属に属する水素細菌を菌体生産させた報告例はな(本
発明が最初である。Hitherto, there have been no reports of cell production of hydrogen bacteria belonging to the genus Xanthobacter using nitrogen gas as the only nitrogen source (the present invention is the first).
この結果、本発明ではこれまでの無機窒素源に代わるも

物菌体の製造コストを大iJにダウンさせることができ
るものである。As a result, the present invention not only makes it possible to effectively utilize nitrogen gas in the air as the only nitrogen source in place of conventional inorganic nitrogen sources, but also uses oxygen gas and carbon dioxide in the air as an energy source and carbon source. This makes it possible to reduce the manufacturing cost of microbial cells to a large iJ.
