A prostaglandin production method according to the present invention comprises reacting an unsaturated fatty acid with cyclooxygenase in the presence of a reducing agent. According to the present invention, it is possible to produce prostaglandins at a high yield.

Prostaglandin production method

Provided is a purification method for water to be used for culture of an aquatic organism, wherein the method includes a nitrification step of oxidizing ammonia to nitric acid using a nitrifying bacterium adhering to a base material containing an alkaline earth metal, and a denitrification step of reducing nitric acid to nitrogen using a denitrifying bacterium adhering to a base material containing a biodegradable resin which has a structural unit derived from dicarboxylic acid.

Purification method for water, purification device for water, and use of said purification device at low water temperature

Provided is3 desaturase having high enzymatic activity even at normal temperature. A polypeptide which consists of an amino acid sequence having an identity of 80% or more with the amino acid sequence represented by SEQ ID NO: 2 and has3 desaturation activity on C20 fatty acid, and a gene thereof.
