Chryseobacterium hispanicum sp. nov., isolated from the drinking water distribution system of Sevilla, Spain.

Strain VP48(T) was isolated from drinking water during a screening programme to monitor the bacterial population present in the water distribution system of Sevilla (Spain). A polyphasic taxonomic study of the isolate resulted in its identification as a member of the genus Chryseobacterium, members of which are widely distributed in soil, water and clinical sources. However, the 16S rRNA gene sequence similarity values of strain VP48(T) to the type strains of Chryseobacterium species were 96 % or lower. Furthermore, phenotypic characteristics clearly indicated that the isolate represents a novel Chryseobacterium species, for which the name Chryseobacterium hispanicum sp. nov. is proposed; strain VP48(T) (=CECT 7129(T)=CCM 7359(T)=JCM 13554(T)) is the type strain. The DNA G+C content of this strain is 34.3 mol%.
