The phrase "a mix of substrates" is correct and usable in written English.
It can be used when discussing a combination of different materials or components, particularly in scientific or technical contexts.
Example: "The experiment required a mix of substrates to observe the varying reactions under different conditions."
Alternatives: "a combination of substrates" or "a blend of substrates".
The mitochondria are present in a physiological environment, are exposed to a relevant mix of substrates and ions and interact with the cytoplasm, plasma membrane and other organelles and cell structures.
The research is based on wheat bran and a mix of damaged ground grains substrates for biogas production.
Our purpose is to develop an appropriate substrate consisting of a mix of organic and inorganic residues.
The substrate used was a mix of 87% cow manure and 13%% fish waste silage (v/v).
Each lid had a screw opening for a stirrer, which gently stirred the water continuously to provide mixing of substrates, and a screw cap-opening with a septum.
Accordingly, lipid peroxidation reduces membrane fluidity and increases membrane permeability [3], which leads to a mixing of enzymes and their substrates.
One was a 2X mix of DNA substrate, PPi and enzyme prepared in the reaction buffer (17 mM Tris-HCl (pH 7.5), 17 mM NaCl, 1 mM dithiothreitol and 20% glycerol) along with different sodium pyrophosphate concentrations and was loaded in one syringe.
Substrate was loaded by gentle mixing of substrate and resin in buffer on an end-over-end rotator for 2 h at 30 °C and 30 rpm (0.5 mL).
Although mixing of substrate and enzymes is crucial for an efficient liquefaction, our previous findings showed that it does not appear that lack of mixing is the cause of the decreasing conversion, at least not at the solids levels documented [ 4].
The temperature of the reaction was maintained at 35°C and impeller speed was 200 rpm for proper mixing of substrate and resting cells.
