Provided is a Streptomyces and its use in synthesis of phosphatidylserine. A fermentation broth produced by the Streptomyces, using soybean lecithin and L-serine as raw materials, can simultaneously convert phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphatidylinositol (PI) in lecithin to efficiently produce phosphatidylserine (PS). The Streptomyces, designated as Streptomyces sp. LN2, is deposited at China General Microbiological Culture Collection Center (CGMCC) on Apr. 1, 2024, with an accession number CGMCC NO. 30230.
