Cellular fatty acid compositions (%) of strains HNIBRBA2951^T, HNIBRBA3233^T and four related type strains

Strains: 1, HNIBRBA2951^T; 2, HNIBRBA3233^T; 3, S. donghicola KACC 17293^T; 4, S. guttiformis KACC 13741^T; 5, S. mediterraneus KCTC 32188^T; 6, S. undariae KCTC 42200^T. Data of columns 1-4 obtained from this study; data of column 5 and 6 obtained from Fukui et al. (2015) and Yoon (2019), respectively. Fatty acids amounting to <1.0% of the total fatty acids in all strains are not shown. -, not detected; nd, no data; tr, traces (<0.5%).
