Abstract
Two Gram-stain-negative, aerobic, yellow and rod-shaped bacteria, designated as strains PBS4-4T and GMJ5T, were isolated from soil samples collected in Goyang-si and Paju-si, Gyeonggi-do, Republic of Korea. Strains PBS4-4T and GMJ5T were both positive for catalase and oxidase. Strain PBS4-4T grew at 15–37 °C and pH 5.0–12.0. Strain GMJ5T grew at 15–37 °C and pH 5.0–11.0. Neither strain required NaCl for growth. 16S rRNA sequence analysis revealed that strains PBS4-4T and GMJ5T form a closely related cluster with the genus
Chryseobacterium
. The average nucleotide identity and digital DNA–DNA hybridization values between strain PBS4-4T and its closely related strains were 79.4–84.5% and 23.2–28.7 %, respectively. For GMJ5T, the values were 78.3–79.3% and 22.0–22.6 %, respectively. The major fatty acids shared by both novel strains were iso-C15 : 0 and summed feature 3 (C16 : 1
ω7c/C16 : 1
ω6c). Strain GMJ5T had one other major fatty acid: iso-C17 : 0 3OH. Based on phenotypic, genomic and phylogenetic results, strains PBS4-4T and GMJ5T represent novel species within the genus
Chryseobacterium
, and the names Chryseobacterium edaphi sp. nov. and Chryseobacterium gilvum sp. nov. are proposed, respectively. The type strain of C. edaphi is PBS4-4T (=KACC 22882T=TBRC 17052T) and the type strain of C. gilvum is GMJ5T (=KACC 22883T=TBRC 17053T).
