A Gram-stain-negative, strictly aerobic, cream yellow colored, non-motile, rod-shaped bacterial strain, designated MAH-1 T was isolated from rhizospheric soil of Coriandrum sativum . A polyphasic taxonomic study was performed on the isolated strain. Optimal growth occurred at 28–30 °C, pH 6.5 and 0% NaCl. The strain showed activity for both catalase and oxidase tests. Cell growth occurs on R2A agar, nutrient agar and Luria–Bertani agar. Cells were able to hydrolyze starch, aesculin, gelatin, and Tween 20. Alignment of 16S rRNA gene sequences indicated that strain MAH-1 T was associated with the genus Flavobacterium and was most closely related to Flavobacterium longum YIT 12745 T (94.5% sequence similarity) and Flavobacterium caeni LM5 T (93.0%). Strain MAH-1 T had a genome size of 3,975,600 bp. Genome contained 67 contigs encoded by 3,522 protein-coding genes with 38 tRNA and 6 rRNA genes. The genomic DNA G + C contents of strain MAH-1 T was 47.1 mol %. The genomic ANI and dDDH values between strain MAH-1 T and one of the close relatives F. caeni LM5 T were 72.2 and 18.8%, respectively. The major fatty acids were C 15:0 iso , C 16:0 iso and C 15:0 anteiso . The predominant respiratory quinone was menaquinone 6 (MK-6). Based on physiological, biochemical and phylogenetic data for this isolate, it was confirmed that strain MAH-1 T was affiliated to the genus Flavobacterium and represented a novel species, for which the name Flavobacterium agri sp. nov. is proposed. The type strain is MAH-1 T (= KACC 19300 T  = CGMCC 1.16617 T ).
