Two novel, designated strains 29W222T and 2943T, were isolated from the marine sediment Aoshan Bay, Jimo, PR China. Growth was observed at pH 6.0-8.5 (optimum, 7.5) for strain 29W222T, 5.5-8.5 (pH 7.0) 2943T. Both displayed growth in 0.5-6 % NaCl with an optimum 1 29W222T; 0.5 grew optimally 33 °C. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that 2943T represented members genus Fulvivirga most closely related to kasyanovii KMM 6220T (97.9 sequence similarity) imtechensis AK7T (95.0 %), (95.7 %) (94.8 %). genomic DNA G+C contents 39.9 37.7 mol%, respectively. chemotaxonomic analysis sole respiratory quinone menaquinone 7 (MK-7), major fatty acid iso-C15 : 0 both strains. Average nucleotide identity average amino values between 78.9 83.6 %, respectively; corresponding 69.8 63.6 Therefore, represent two novel species Fulvivirga, which names marina sp. nov. (29W222T=KCTC 62848T=MCCC 1K05194T) sediminis (2943T=KCTC 62847T= MCCC 1K05144T) are proposed,
