Table 3. Cellular fatty acid compositions (%) of APC 3343T and closely related type strain members of the genus Winogradskyella.
Strains: 1, APC 3343T (data from this study); 2, W. algae Kr9-9T [9]; 3, W. damuponensis F081-2T [20]; 4, W. eximia KMM 3944T [1]; 5, W. litoriviva KMM 6491T [7]; 6, W. endarachnes HL2-2T [10]. Major fatty acids (>10%) are highlighted in bold. Fatty acids amounting <1.0% for all reference strains are not shown. TR, Trace amount (<1%); −, not detected. ECL, estimated carbon length.
