These are bacteria whose classification has been based on their ability to retain the crystal violet dye after a brief wash with alcohol in the differential gram staining. Gram-positive bacteria stain purple while the Gram-negative bacteria stain Pink, after losing the purple color during the alcoh...
Based on the results of gram staining and on the morphology of the cells as seen through the microscope, gram-positive bacteria may be grouped as either gram-positive cocci or gram-positive bacilli. Gram-positive cocci are gram-positive bacteria that appear spherical. Examples includeStreptococcussp...
Gram-negative bacteria historically have been separated from Gram-positive bacteria by their inability to absorb crystal violet dye. This definition has proven useful in diagnostics and defines bacterial genera in Prokaryote groups IV and V, which are often associated with insects (Lysenko, 1963; Bouc...

Definition A Gram-positive bacterium is a prokaryotic cell whosecell wallconsists of mainlypeptidoglycanand lacks the outer membrane characteristic of the Gram-negative cells. Bacteria can be divided into two major groups, called Gram positive and Gram negative. The original distinction between both gro...

Bacillus subtilis is the best-characterized member of the Gram-positive bacteria. Its genome of 4,214,810 base pairs comprises 4,100 protein-coding genes. Of these protein-coding genes, 53% are represented once, while a quarter of the genome corresponds
