Exactly. When doing a gram stain on B. subtilis, this bacterium resists decolorization (keping the first stain and NOT taking on the color of the secondary stain). Therefore, this...
Gram-positive bacteria have more peptidoglycan layers in their cell walls than Gram-negative and so are able to retain a crystal violet dye during the Gram stain process. Gram-positive bacteria...
Gram-positive is a result of the Gram staining technique, developed by Danish scientist Hans Christian Gram (1853 - 1938). Bacteria can have two types of cell walls. Gram-Positive bacteria have a...
