After onsverving that it was a gram positive rod, I determined
it was of the bacillus genus. The following bacillus bacteria we
could have are:

•Bacillus cereus

•Bacillus circulans

•Bacillus coagulans

•Bacillus megaterium

•Bacillus subtilis

So far I’m leaning more towards Bacillus cereus, but any
additional help would be appreciated. Also included is a photo of
the gram stain, broth tube, and also a photo of the colony
morphology
