Thaumarchaeota is the dominant phylum in the exfoliating weathering rock and saprolite environment just as in bulk soil, and its archaeal class and OTU composition is extremely similar—particularly to soils of similar pH. In all three environments, soil, rock surface, and saprolite, pH is the best predictor of archaeal community structure.

In this work, we demonstrate the use of a green liquid/liquid-extraction to transfer lignin from the organic phase of the OrganoCat process into differently concentrated alkaline solutions for further utilization.
