Morphology

Serratia + marcescens

This is a Latin binomial taxonomic name: as a proper scientific label it functions like an arbitrary name rather than a compositional phrase. A B1 learner who knows 'Serratia' only as a bacterial genus and does not know the Latin epithet 'marcescens' (or its meaning) cannot derive the species meaning from the constituents, so it is not transparently interpretable.

Etymology

Serratia marcescens is a name made of a person's name and a Latin word. The genus Serratia was named after Serafino Serrati, and marcescens means 'decaying' in Latin because the red colour the bacterium makes often fades, so the name describes this red, fading bacterium.
