Differential Characteristics of strains HNIBRBA2951T, HNIBRBA3233T and four related type strains

Strains: 1, HNIBRBA2951T; 2, HNIBRBA3233T; 3, S. donghicola KACC 17293T; 4, S. guttiformis KACC 13741T; 5, S. mediterraneus KCTC 32188T; 6, S. undariae KCTC 42200T. 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. All strains were positive for catalase and oxidase activities. All strains were negative for nitrate reduction; indole production; glucose fermentation; α-chymotrypsin, β-glactosidase, N-acetyl-glucosaminidase, β-glucuronidase and α-fucosidase activities; and assimilation of D-mannose and capric acid. +, Positive; –, negative; w, weakly positive reaction; nd, no data.
