Strain 25-1T grew optimally at pH 7.0-8.0, at 28-30 ℃ and in the presence of NaCI concentrations from 0.0% to 0.5%. 16S rRNA gene sequence analysis indicated that strain 25-1m belongs to the genus Chryseobacterium within the family Flavo- bacteriaceae and is related most closely to C. camis G81m （96.4% similarity）, C. lathyri RBA2-6T （95.8% similarity）, and C. zeae JM1085T （95.8% similarity）. Its genomic DNA G＋C molar composition was 36.2%. The major cellular fatty acids were iso-C15：0 （44.0%）, iso-C17：0 3OH （19.8%） and C16：1 ω7c/16：1 ω6c （12.7%）. The only isoprenoid quinone was menaquinone 6 （MK-6）. The major polar lipids were phosphatidylethanolamine, two unidentified amino lipids and two unidentified lipids. The DNA-DNA relatedness between strain 25-1m and C. lathyri RBA2-6T was 38%. Phenotypic, genotypic, and phylogenetic characteristics indicated that strain 25-1T is a novel member of the genus Chryseobacterium, for which the name C. chengduensis sp. nov. is proposed. The type strain is 25-1T （ccmoc AB2015133T=DSM 100396T）.展开更多
