Prauserella salsuginis sp. nov., Prauserella flava sp. nov., Prauserella aidingensis sp. nov. and Prauserella sediminis sp. nov., isolated from a salt lake.

Strains YIM 90625(T), YIM 90630(T), YIM 90636(T) and YIM 90694(T) were isolated from a salt lake in Xinjiang province, north-west China, and were subjected to a polyphasic analysis to determine their taxonomic positions. All isolates were moderately halophilic and were able to grow at NaCl concentrations up to 15 or 20 % (w/v). The genomic DNA G+C contents of the strains ranged from 69.1 to 70.1 mol%. Based on the results of 16S rRNA gene sequence analysis, DNA-DNA relatedness, phenotypic characteristics and chemotaxonomic data, the isolates are proposed to represent four novel species of the genus Prauserella for which the names Prauserella salsuginis sp. nov. (type strain YIM 90625(T)=CCTCC AA 208051(T)=DSM 45264(T)), Prauserella flava sp. nov. (type strain YIM 90630(T)=CCTCC AA 208052(T)=DSM 45265(T)), Prauserella aidingensis sp. nov. (type strain YIM 90636(T)=CCTCC AA 208053(T)=DSM 45266(T)) and Prauserella sediminis sp. nov. (type strain YIM 90694(T)=CCTCC AA 208054(T)=DSM 45267(T)).
