Relationships between algal coals and resistant cell wall biopolymers of extant algae as revealed by Py-GC-MS

The resistant biopolymers (PRB A , PRB B and PRB L ), isolated from the walls of three different races of the extant alga Botryococcus braunii and two algal coals (Torbanite, Kukersite) were examined using Py-GC and Py-GC-MS. These pyrolytic methods appear as particularly efficient tools in comparat...

Description
Summary:The resistant biopolymers (PRB A , PRB B and PRB L ), isolated from the walls of three different races of the extant alga Botryococcus braunii and two algal coals (Torbanite, Kukersite) were examined using Py-GC and Py-GC-MS. These pyrolytic methods appear as particularly efficient tools in comparative studies of such materials. The structure of PRB L was thus shown to be different from those of PRB A , PRB B and Torbanite while the spectroscopic features (FT IR, solid state 13C NMR) of all these products are similar. It also appeared that Kukersite does not consist of selectively preserved PRB L .
