The phrase "as primary substrates" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in discussions about biochemical processes or materials.
Example: "In the experiment, glucose and fructose were utilized as primary substrates for fermentation."
Alternatives: "as main substrates" or "as key substrates".
Strain 55730 demonstrated enhanced versatility with respect to proliferation with different carbohydrates as primary substrates, such as sucrose, raffinose, maltose, lactose, galactose, and galacto-oligosaccharides compared to strain 6475 (Figure S7).
Aromatic amino acids act as primary substrates for phenylpropanoid pathway.
The CorA family of divalent cation transporters utilizes Mg2+ and Co2+ as primary substrates.
Therefore, the ∆6 and ∆9 pathways can simultaneously use both LA and ALA as primary substrates.
During the accumulation process, glycerol-3-phosphate (G-3-P) and acyl-CoA serve as primary substrates in the Kennedy pathway.
The degradation was not enhanced by the presence of acetate or toluene as primary substrates, and the degradation of the pharmaceuticals in the presence of nitrate as electron acceptor was not observed.
We conclude that provision of methane as primary substrate and addition of ω-hydroxyalkanoate as co-substrates is a promising route for synthesis of polymers with tunable physical properties.
As primary substrate does not directly bind to the Fe(II), altered local contacts within the active site likely stimulate O2 activation.
It is thus necessary to identify for each generic compound the corresponding set of specific compounds, as much for primary substrates as for cofactors.
The highest TCDD degradation rate [up to 86% of TCDD removal (with an initial concentration of 96 μg/kg of soil)] was observed in the microcosms with anaerobic activated sludge as the microbial inocula and sludge cakes as the primary substrates.
