NMR spectra of glycolipids produced by Rouxiella sp. DSM 100043 present in subfraction 63–65 E. Close-up of the carbohydrate region in a ¹H spectrum and b two dimensional ¹H/¹H COSY spectrum and assignment of signals for two sugar moieties C^1–6 in red and ^a C ¹⁻⁶ in blue. c Two dimensional ¹H/¹³C HSQC spectrum revealing two anomeric nuclei: C¹ and ^a C ¹, the latter downshifted and indicating an acetylation. d Potentional molecular structures and assigned C atoms of talopyranose (red) and 1′ acetyl talosepyranose (blue)
