Morphology
The meaning 'a nutrient substance used for growing microorganisms' is directly compositional from 'culture' (growing organisms) + 'medium' (material supporting growth); the noun+noun combination indicates the medium used for culture. This structure is common across languages (e.g., Spanish 'medio de cultivo', French 'milieu de culture'), so a B1 learner who knows both constituents can reliably infer the MWE meaning.
Etymology
Culture medium comes from lab work: culture means a group of tiny living things people grow, and medium is the material that helps them grow. Think of it like food or soil in a dish for microbes, so the phrase means 'a nutrient substance used for growing microorganisms'.
