The G+C content of the DNA was 46·5 mol%. The organism grew between 4 and 33 °C, tolerated 10 % NaCl, was slightly alkaliphilic and was not able to degrade starch, gelatin, agar or Tween 80. Phosphatidylethanolamine (53·4 %) and phosphatidylglycerol (46·6 %) were the predominant phospholipids. The major fatty acids were 16 : 0 (15·5 %), 16 : 1ω7 (26·7 %) and 18 : 1ω7 (47·1 %). The phylogenetic, genetic and physiological properties of the organism placed it within a novel species, proposed as Marinomonas pontica sp. nov., the type strain of which is 46-16T (=LMG 22531T=KMM 3492T=UCM 11075T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.63326-0
