Zunongwangia　is　a　group　of　marine　bacteria　with　important　industrial　application　potential　and　ecological　functions.　In　this　study,　a　Gram-stain-negative,　rod-shaped,　non-motile,　strictly　aerobic　and　bright　yellow　pigmented　bacterial　strain　within　this　genus,　designated　C2-37M9(T),　was　isolated　from　a　surface　seawater　sample　from　the　Philippine　Basin　in　the　Western　Pacific　Ocean.　Strain　C2-37M9(T)　grew　at　10-44　degrees　C　(optimum,　28-30　degrees　C),　pH　6-9　(pH　7)　and　in　the　presence　of　0-12%　NaCl　(w/v;　2-3%).　Phylogenetic　analysis　based　on　16S　rRNA　gene　sequences　indicated　that　it　belonged　to　the　genus　Zunongwangia　and　had　95.7-98.7%　sequence　similarity　to　all　type　strains　of　this　genus,　with　the　highest　value　corresponding　to　Zunongwangia　profunda　(98.7%).　Digital　DNA-DNA　hybridization,　average　nucleotide　identity　and　average　amino　acid　identity　values　between　strain　C2-37M9(T)　and　all　valid　type　strains　were　27.5-32.3,　83.8-86.7　and　86.9-89.0　%,　respectively.　The　principal　fatty　acids　(＞5%)　were　iso-C-15:0,　iso-C-17:0　3-OH,　anteiso-C-15:0,　summed　feature　9　(C-16:0　10-methyl　and/or　iso-C-17:1　omega　9c),　iso-C-15:1　G　and　summed　feature　3　(C-16:1　omega　6c　and/or　C-16:1　omega　7c).　The　predominant　respiratory　quinone　was　MK-6.　The　polar　lipids　were　one　phosphatidylethanolamine,　two　unknown　glycolipids,　three　unidentified　aminolipids　and　six　unidentified　lipids.　The　genomic　DNA　G+C　content　of　strain　C2-37M9(T)　was　36.7　mol%.　Based　on　phylogenetic　results　and　genomic-based　relatedness　indices,　as　well　as　phenotypic　and　genotypic　characteristics,　strain　C2-37M9(T)　represents　a　novel　species　within　the　genus　Zunongwangia,　for　which　the　name　Zunongwangia　pacifica　sp.　nov.　is　proposed.　The　type　strain　is　C2-37M9(T)　(=MCCC　M21534(T)=KCTC　82852(T)).
