DIC measurement: an aliquot of the slurry was filtered with a 0.2-µm filter to remove cells and other particles. After filtration, 1 mL of samples were acidified with 100 μL 45%...

Incubation time was controlled based on the development of δ13C values of CO2 in the headspace. δ13C of CO2 was measured by Thermo Finnigan Trace GC coupled to a Thermo Finnigan...

Amino acids derivatization and analysis: Sediment slurries were centrifuged to separate the sediments from the medium and the sediments were freeze-dried and homogenized. 50 mg...

Polar lipid-derived fatty acids (PLFAs) and their stable carbon isotopes are frequently combined to characterize microbial populations involved in the degradation of organic...

C15:1-I and C15:1-II are tentatively assigned as C15:1ω8 and C15:1ω6 (molecule structures were not identifiable entirely in terms of their double bound-positions). iC17:1-I and...

999.0 = Not detected.The deviations of VFA concentrations measured in duplicate of the incubated samples were up to ± 3.3 mg C l−1. Deviations of the δ13C values in these...

The analytical precision of the DIC concentration measurements accounted for ±0.01 mg l−1. Deviations of the δ13C values of DIC in the incubated samples (duplicate measurements)...

Multicellularity is a key evolutionary innovation, leading to coordinated activity and resource sharing among cells, which generally occurs via the physical exchange of chemical...
