ABSTRACT Bacillus cereus strain IM8 isolated from an ice core of the Upper Fremont Glacier in Wyoming showed 97.52% average nucleotide identity with B. cereus sensu stricto , a lineage typically not associated with psychrotolerance. Phenotypic characterization highlighted high cytotoxicity toward human intestinal epithelial Caco-2 cells and resistance to ampicillin.
Chandross-Cohen et al. (Mon,) studied this question.
