Abstract

A strain of an achlorophyllic alga, named PR24, was isolated from cow milk samples from the state of Minas Gerais, Brazil. Based on 18S rDNA, 28S rRNA, D1/D2 region of the LSU rDNA and SSU rRNA gene sequence similarities, this strain was found to be a member of the genus and closely related to SAG2064. However, the novel strain could easily be distinguished from recognized species by internal transcribed spacer, species-specific PCR, single-strand conformation polymorphism-PCR analysis and phenotypic characteristics. The inability to grow in Sabouraud broth at pH 4.0 and the different cellular fatty acid composition clearly distinguished PR24 from the reference strain of . The combination of genotypic and phenotypic data indicates that strain PR24 represents a subspecies of , for which the name subsp subsp. nov. is proposed. The respective type strain is PR24 (=DSM 103592=IHEM 26958).
