Bacteriastrum is a genus ofdiatoms in familyChaetocerotaceae.[1] There are more than 30 described species in genusBacteriastrum, but many of these are not currently accepted, and new species are still added to the genus.[2] The type species for the genus isBacteriastrum furcatum Shadbolt.
Bacteriastrum is a widely distributed marine, planktonic genus. This genus is often associated withChaetoceros but differs in radial symmetry and fenestration of setae. The colonies tend to lie in girdle view, and the cells are separated by the curvature of the basal part of the setae, leaving a small gap between the cells. The cells are cylindrical and linked to form filaments. Each cell has several long, radiating setae which may be simple or bifurcate (branched), the setae from adjacent cells are fused. The plastids are discoid. At least one species,B. solitarium, exists as single cells.[3]
