A motile Gram‐positive bacterial strain (KL8) was isolated from indoor dust. It was identified by API‐test50 CHB as a species of Bacillus. This Bacillus sp. strain KL8 was described using different electron microscopic techniques: negative staining, thin sectioning, metal shadowing and freeze‐etching. An additional surface layer (S‐layer) was the outermost layer of the cell wall of this flagellated bacterium. The hexagonally arranged protein lattice covering the cells had a lattice constant about 9–10 nm, which falls in the same range as that of Bacillus anthracis .
