Microorganisms are ubiquitous in deep subsurface environments, but their role in the global
carbon cycle is not well-understood. The natural abundance δ13C and Δ14C values of …

Abstract Analysis of fatty acid methyl ester (FAME) profiles extracted from soils is a rapid and
inexpensive procedure that holds great promise in describing soil microbial community …

A 13C natural abundance experiment including GC-c-IRMS analysis of phospholipid fatty
acids (PLFAs) was conducted to assess the temporal dynamics of the soil microbial …

The whole-cell lipid extraction to profile microbial communities on soils using fatty acid (FA)
biomarkers is commonly done with the two extractants associated with the phospholipid fatty …

While phospholipid fatty acid (PLFA) profiling is a well‐established method used for the
determination of bacterial and eukaryotic organisms in soil ecology, phospholipid etherlipid …

Recently, 6-methyl branched glycerol dialkyl glycerol tetraethers (brGDGTs) were separated
from 5-methyl brGDGTs, which are used in brGDGT-based proxies. Here we analyzed …

The 1-O-monoalkyl glycerol ethers (MAGEs) were initially viewed as the biomarkers for
sulfate-reducing bacteria (SRB) mediating anaerobic oxidation of methane in the marine …

Groundwater ecosystems host diverse and complex microbial communities that play
important roles in the biogeochemical processing of organic matter and in the maintenance …

Loess–palaeosol sequences are considered important terrestrial archives for studying
Quaternary climate. Recent studies have shown that calcified roots (rhizoliths) can be …

The hydrogen isotopic composition of leaf wax–derived n-alkane (δ 2 H n-alkane) and
oxygen isotopic composition of hemicellulose–derived sugar (δ 18 O sugar) biomarkers are …
