Chryseobacterium

Chryseobacterium is a genus of Gram-negative bacteria. Chryseobacterium species are chemoorganotrophic, rod shape gram-negative bacteria. Chryseobacterium form typical yellow-orange color colonies due to flexirubin-type pigment. The genus contains more than 100 described species from diverse habitats, including freshwater sources, soil, marine fish, and human hosts.

== History == The genus Chryseobacterium was originally created in 1994 by Vandamme et al. for six bacterial taxa that, at that time, were classified as members of the genus Flavobacterium: F. balustinum, F. indologenes, F. gleum, F. meningosepticum, F. indoltheticum, and F. scophthalmum. In 2005 an additional genus, Elizabethkingia, was created for two species within the genus Chryseobacterium; namely, C. meningosepticum and C. miricola. In 2002 standards and guidelines for description of novel taxa in the family of Flavobacteriaceae were published by Bernardet et al. By 2006, the genus Chryseobacterium had expanded to 10 species, by 2014 more than 60 species and currently more than 100.
