The authors wish to make the following corrections to this paper [1]:
There are mistakes regarding the possibility for growth on several substrates shown in Table 1 and in the table legend because some lines were changed when formatting the table.
Table 1.
Differentiating characteristics between phylogenetically related species from the genus Thiothrix (Clade I). All strains utilize acetate, lactate and pyruvate. Glyoxylate, glycolate, benzoate, salicylate, methanol, isopropanol (propan-2-ol), glycerol, lactose, D-galactose, D-(+)-glucose, D-mannose, serine, lysine, tryptophan, methionine, tyrosine, ornithine, glutamine and alanine do not support the growth of all strains. All strains are capable of chemolitoautotrophic growth with thiosulfate and bisulfide. All strains are capable of respiration of nitrate to nitrite. No strains hydrolyze gelatin or starch. All strains are catalase-negative. None of the strains grow at 3% NaCl. Thiothrix litoralis AST is able to survive with up to 3% NaCl in the medium. The major fatty acids for all strains are C16:1ω7, C16:0, C18:1ω7. Data are from [26,27].
