The first step during the Gram staining technique is applying the primary stain, crystal violet, for twenty to sixty seconds. After this is completed, rinse with water and proceed to add the...
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...
Gram staining procedure uses four chemicals; crystal violet, iodine, alcohol, and safranin, to stain bacteria Gram staining is still the cornerstone of bacterial identification and taxonomic division. This differential staining technique separates most bacteria into two groups based on cell wall ...
