Alternatively, the authors argued that if HCO3− (DIC) from seawater was the main carbon source of carbonate in Tubastrea, the extracellular CA could eliminate the protons that are released by the conversion of HCO3− to carbonate.
Relatively high δ13Ccarb values of the authigenic carbonates (largely −1 ‰) compared with those of organic matter in the rocks (ca. −26 ‰) suggest that the main carbon source of the carbonates was DIC in the water column.
The relatively high δ13Ccarb values of the carbonates (largely about −1 ‰) indicate that their main carbon source was seawater DIC.
In the nutrition study, the carbon mass balance indicated CO2 was the main carbon source.
A batch culture confirmed that lactate was used as the main carbon source and a global yield of 0.4molH2·mollactate−1 was obtained.
The yeast cells are produced in a series of fed batch reactors which are fed with oxygen and glucose as the main carbon source.
These organic acids are suitable as the main carbon source for growth and production of polyhydroxyalkanoates (PHAs) by organisms like Ralstonia eutropha.
Trypanosoma cruzi, the etiological agent of Chagas disease, uses proline as its main carbon source, essential for parasite growth and stage differentiation in epimastigotes and amastigotes.
However, the main carbon source present in the medium is sorbitol, a non-inducing, non-repressing carbon source.
The main carbon source of the randomly oriented and bundled calcites in the Mudstone Unit is likely the seawater DIC.
CO2, the main carbon source of autotrophic microalgae, plays an important role in microalgal growth and lipid synthesis.
