Abstract:
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.
