Morphology

division + eubacteria

The phrase is compositionally transparent: 'division' as a taxonomic rank combined with the proper noun 'Eubacteria' yields the meaning 'the taxonomic division consisting of Eubacteria'. Although the terms are technical, the classification pattern (rank + group name) is regular and cross-linguistically familiar, so a learner who knows both constituents can infer the MWE's meaning.

Etymology

Division Eubacteria comes from older biology naming, where scientists put the 'true' bacteria into one large division called Eubacteria. Think of a folder labeled Eubacteria holding simple, single-cell organisms with hard cell walls, and that image helps you remember it means a major 'group' of simple bacteria.
