  1. Molar C/N ratios of the product isolated from Methylosinus trichosporium OB3b cultures with resin extraction and of the four fractions collected during the following HPLC fractionation procedure as well as the molar C/N ratio of methanobactin according to the molecular structure proposed by Behling et al. [16]. Additionally, the relative C and N contribution of fractions 1-4 to the total content of the resin extract is shown.
