The phrase "aeration tubes" is correct and usable in written English.
It can be used in contexts related to gardening, aquaculture, or any situation where air needs to be introduced into a liquid or soil medium.
Example: "The aquaponics system relies on aeration tubes to ensure that the fish have enough oxygen in the water."
Alternatives: "air tubes" or "oxygenation tubes".
One bed did not contain aeration tubes.
All the beds included a cobbles bottom layer, where perforated PVC aeration tubes were placed.
The beds included a cobbles lower layer, where perforated PVC aeration tubes were placed, and two gravel layers on top.
The presence of reeds and aeration tubes was found to improve the performance, while plant species did not affect efficiency.
The presence of reeds, aeration tubes and a fine-grained material improved the system efficiency, while the material composition did not have any effect on efficiency.
In particular, distance from the aeration tube to the liquid surface was important.
This COD removal was attributed to the attached and suspended growth of the algal biomass on the aeration tube as well as in the mixture.
Gas was diffused into the fermenting broth through an aqueous aeration tube commonly used in the small household aquarium, placed at the bottom layer throughout the periphery.
Although the size of bubbles affects the retention time, an aeration tube (that is commonly used in small household aquariums) has been selected to create a circular gas supply system (diameter is 4 cm smaller than the reactor's inside diameter) and placed at the center of the bioreactor with the help of a holder keeping a clearance of about 1 cm from the bottom (Additional file 1: SI-1-2).
Add the hydrated cysts and keep them in suspension (i.e. with an aeration tube) for 5-15 min. Check the temperature regularly, since the reaction is exothermic; never exceed 40°C (if needed add ice to decapsulation solution).
Cells of CB1000, CB2000, CB3000, and CB4000 were cultured in LB broth at 37°C (Miller, 1992) with aeration in polypropylene tubes.
