Graminin B was isolated from acetone extracts of Paraconiothyrium sp. (CF-217411) by fractionation on SP207SS resin followed by repeated semi-preparative HPLC. The molecular formula of 1 was deduced to be C18H26O4 by accurate mass measurement (ESI-TOF, Supplementary Figure S4), requiring ...
Freeze-fracture TEM supports that the macromolecular network structure of the starch hydrogel may represent a useful surrogate of the Gram-negative bacterial envelope. A random forest analysis of in vitro data revealed molecular mass, minimum projection area, and rigidity as the most critical ...
