Chryseobacterium artocarpi sp nov., isolated from the rhizosphere soil of Artocarpus integer
A bacterial strain, designated UTM-3T, isolated from the rhizosphere soil of Artocarpus integer (cempedak) in Malaysia was studied to determine its taxonomic position. Cells were Gramstain-negative, non-spore-forming rods, devoid of flagella and gliding motility, that formed yellowpigmented colonies...

| Summary: | A bacterial strain, designated UTM-3T, isolated from the rhizosphere soil of Artocarpus integer (cempedak) in Malaysia was studied to determine its taxonomic position. Cells were Gramstain-negative, non-spore-forming rods, devoid of flagella and gliding motility, that formed yellowpigmented colonies on nutrient agar and contained MK-6 as the predominant menaquinone. Comparative analysis of the 16S rRNA gene sequence of strain UTM-3T with those of the most closely related species showed that the strain constituted a distinct phyletic line within the genus Chryseobacterium with the highest sequence similarities to Chryseobacterium lactis NCTC 11390T, Chryseobacterium viscerum 687B-08T, Chryseobacterium tructae 1084-08T, Chryseobacterium arthrosphaerae CC-VM-7T, Chryseobacterium oncorhynchi 701B-08T, Chryseobacterium vietnamense GIMN1.005T, Chryseobacterium bernardetii NCTC 13530T, Chryseobacterium nakagawai NCTC 13529T, Chryseobacterium gallinarum LMG 27808T, Chryseobacterium culicis R4-1AT, Chryseobacterium flavum CW-E2T, Chryseobacterium aquifrigidense CW9T, Chryseobacterium ureilyticum CCUG 52546T, Chryseobacterium indologenes NBRC 14944T, Chryseobacterium gleum CCUG 14555T, Chryseobacterium jejuense JS17-8T, Chryseobacterium oranimense H8T and Chryseobacterium joostei LMG 18212T. The major whole-cell fatty acids were iso-C15 : 0 and iso-C17 : 1ω9c, followed by summed feature 4 (iso-C15 : 0 2-OH and/or C16 : 1 ω7t) and iso-C17 : 0 3-OH, and the polar lipid profile consisted of phosphatidylethanolamine and several unknown lipids. The DNA G+C content strain UTM-3T was 34.8 mol%. On the basis of the phenotypic and phylogenetic evidence, it is concluded that the isolate represents a novel species of the genus Chryseobacterium, for which the name Chryseobacterium artocarpi sp. nov. is proposed. The type strain is UTM-3T (=CECT 8497T=KCTC 32509T). |
