Gram staining has guided microbiology for over a century by coloring cells purple or pink, a read-out thought to distinguish monoderms from diderms. Here we show this rule fails repeatedly across Bacillaceae lineages historically deemed “Gram+”@commsbio.nature.com www.nature.com/articles/s42...
Gram-negative-staining Bacillaceae with thick cell wall and monoderm architecture uncover evolutionary diversity and challenge Gram-based classification - Communications Biology
Genomic and microscopy evidence shows that the Bacillaceae, assumed to only stain Gram-positive, actually have some lineages staining Gram-negative, yet unexpectedly maintaining a thick wall and no ou...
