Cells were Gram-stain-negative, strictly aerobic and rod-shaped with a polar flagellum. Optimal growth occurred in the presence of 3–6 % (w/v) NaCl, at pH 6–8 and at a temperature of 37 °C. The predominant polar lipids were phosphatidylglycerol and phosphatidylethanolamine. Ubiquinone 8 (Q-8) was the sole respiratory quinone. The major fatty acids (>10 % of the total fatty acids) were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. The DNA G+C content was 47.6 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain GS-14T had the highest sequence similarity to Aestuariibacter aggregatus WH169T (96.63 %), Aliiglaciecola coringensis AK49T (96.56 %) and Alteromonas lipolytica JW12T (96.22 %). In addition, the OrthoANIu value and dDDH values calculated from the genomes of strain GS-14T and A. aggregatus WH169T were 79.5 and 21.9 %, respectively. Based on the polyphasic taxonomic results, strain GS-14T is considered to represent a novel species in a new genus, for which the name Marisediminitalea mangrovi gen. nov., sp. nov. is proposed. The type strain of Marisediminitalea mangrovi is GS-14T (=KCTC 72401T=MCCC 1K03622T). Because Aestuariibacter aggregatus WH169T clustered with strain GS-14T in the phylogenetic trees and was clearly separated from the two species within the genus Aestuariibacter , it is reclassified as a member of the genus Marisediminitalea as Marisediminitalea aggregata comb. nov. (type strain WH169T=CGMCC 1.8995T=LMG 25283T). The type species of the genus Marisediminitalea is Marisediminitalea aggregata gen. nov., comb. nov.", }
