Provided is a novel production system that does not involve, or can minimize, the transport of liquid ammonia in the production of an organic compound or the production of a microorganism by microbial fermentation. A production system for an organic compound or a microorganism includes: an ammonia synthesis apparatus in which an ammonia-containing gas is synthesized by reaction of a source gas containing hydrogen and nitrogen in the presence of a supported ruthenium catalyst; and a culture apparatus that cultures a microorganism having organic compound productivity using ammonia originating from the ammonia-containing gas obtained by using the ammonia synthesis apparatus.

A production system for a product selected from a nitrogen-containing product and a fermented and cultured product that does not involve (or can minimize) the transport of liquid ammonia can include: an ammonia synthesis apparatus in which an ammonia-containing gas is synthesized by reaction of a source gas containing hydrogen and nitrogen in the presence of a supported metal catalyst containing as a support one or more selected from the group consisting of: i) a conductive mayenite compound; ii) a two-dimensional electride compound or a precursor thereof; and iii) a complex formed of a support base containing at least one metal oxide selected from ZrO, TiO, CeO, and MgO and a metal amide represented by a formula M(NH)(where M represents one or more selected from Li, Na, K, Be, Mg, Ca, Sr, Ba, and Eu; and x represents a valence number of M) supported by the support base.

A pressure regulating diaphragm comprises a central base plate section in the form of a hard disc, a peripheral sealing section having the form of a ring located concentrically with said plate section and an intermediate section located between said peripheral sealing section and said central base plate section, said intermediate section consisting of a film having a thickness of from 10 to 100 microns and made of a plastic resistant to chemicals and defining a deformable, flexible portion, whereby a desired shape can be obtained therein.
