I bought Bacillus subtilis ATCC 6633 bacteria, I grew them on Hichrome bacillus Agar media: green colonies with white crincle or wavy edges and the media changed from pink to yellowish. Is this really bacillus subtilis? from a bacillus cereus-like colony with a bluish-green core and white edges, I have doubts.
If you look at the COA and the bacillus subtilis literature there are no white edges.
