1. Bacillus subtilis stained with crystal violet @ 100xTM. It is not possible to see individual bacteria at this magnification, but viewing at 100XTM is a necessary step in focusing to scope to see at higher magnifications. 2. Bacillus subtilis stained with crystal violet @ 1000xTM. Note large number of endospores.
