substrate
In biochemistry, the starting substance that is converted in a reaction catalyzed by an enzyme.
Laktose ist das Substrat für das Enzym Laktase, das sie in Glukose und Galaktose spaltet.

substrate
In linguistics, a language that is overlaid by another language in a region but still leaves traces in that language's vocabulary, grammar, or pronunciation.

In metaphysics, it is debated whether there is a substrate independent of its properties.
The word comes from the Latin 'substratum', meaning 'that which is laid underneath'. This basic idea of a base or foundation connects all meanings: the soil for a plant, the starting substance for a reaction, or the old language for a new one.

The researchers analyzed the substrate on which the rare lichens were growing.
'Substrat' (substrate) is a technical term from science. It is hardly used in normal everyday life. You mainly encounter it in texts from biology, chemistry, linguistics, or philosophy.
Im Biologieunterricht lernten wir, wie man ein Nährsubstrat für Bakterienkulturen herstellt.
In biology class, we learned how to make a nutrient substrate for bacterial cultures.
You can always recognize the exact meaning of 'Substrat' (substrate) from the context. Words like 'Pflanze' (plant), 'wachsen' (to grow), or 'Erde' (soil) point to the biological meaning. Terms like 'Enzym' (enzyme) or 'Reaktion' (reaction) indicate biochemistry.
Jede Orchideenart benötigt ein anderes Substrat.
Each orchid species needs a different substrate.
In biology and horticulture, 'Substrat' (substrate) is often combined with adjectives such as 'nährstoffreich' (nutrient-rich), 'sauer' (acidic), or 'mineralisch' (mineral). Typical verbs are 'wachsen auf' (to grow on) or 'benötigen' (to need).
Diese Kakteenart wächst am besten auf einem mineralischen Substrat.
This cactus species grows best on a mineral substrate.
medium
In a laboratory experiment, Medium can be the surrounding substance in which a reaction takes place. Substrat, on the other hand, is the starting substance that an enzyme converts in the process. Medium is appropriate for the reaction environment, while Substrat is appropriate for the substance being converted.
Das Enzym wandelt den Zucker als Substrat in ein anderes Produkt um.
The enzyme converts the sugar, which serves as the substrate, into another product.
Die Lösung dient als Medium für die Reaktion mit dem Enzym.
The solution serves as the medium for the reaction with the enzyme.
