Gram-negative-staining Bacillaceae with thick cell wall and monoderm architecture uncover evolutionary diversity and challenge Gram-based classification [PDF]
Communications BiologyGram staining has guided microbiology for over a century by coloring cells purple or pink, a read-out thought to distinguish monoderms (single membrane, thick peptidoglycan) from diderms (inner and outer membranes with thin wall).
