Morphology
The compound combines a clear modifier 'hay' (dried grass) with the head noun 'bacillus' (a rod-shaped bacterium), so its basic meaning — a bacterium associated with hay or decaying plant matter — is directly derivable from the constituents. This noun+noun compositional pattern is common and cross-linguistically transparent, so a B1 learner who knows both words would readily infer the intended referent (the specific species detail is specialist knowledge beyond the transparent compositional core).
Etymology
Hay bacillus comes from bacteria often found in old hay and decaying plants, and bacillus simply means 'a kind of bacteria'. These tiny organisms help break down plant material and some strains make antibiotics, so the name now refers to the common soil bacterium 'Bacillus subtilis'.
