abstract= Two bacterial strains, designated Sa 1147-06T and Sa 1143-06, were isolated from Atlantic salmon (Salmo salar) farmed in Lake Chapo, Chile, and were studied using a polyphasic approach. Both isolates were very similar; cells were rod-shaped, formed yellow-pigmented colonies and were Gram-reaction-negative. Based on 16S rRNA gene sequence analysis, strains Sa 1147-06T and Sa 1143-06 shared 100 % sequence similarity and showed 98.9 and 97.5 % sequence similarity to Chryseobacterium jeonii AT1047T and Chryseobacterium antarcticum AT1013T, respectively. Sequence similarities to all other members of the genus Chryseobacterium were below 97.3 %. The major fatty acids of strain Sa 1147-06T were iso-C13 : 0, iso-C15 : 0, anteiso-C15 : 0 and iso-C17 : 1 ω9c, with iso-C15 : 0 3-OH, iso-C16 : 0 3-OH and iso-C17 : 0 3-OH constituting the major hydroxylated fatty acids. DNA–DNA hybridizations with C. jeonii JMSNU 14049T and C. antarcticum JMNSU 14040T gave relatedness values of 20.7 % (reciprocal 15.1 %) and 15.7 % (reciprocal 25.7 %), respectively. Together, the DNA–DNA hybridization results and differentiating biochemical properties showed that strains Sa 1147-06T and Sa 1143-06 represent a novel species, for which the name Chryseobacterium chaponense sp. nov. is proposed. The type strain is Sa 1147-06T (=DSM 23145T =CCM 7737T).,
