Gram staining is carried out by first heat-fixing bacterial cells to a slide. WebSpecifically, gram-positive bacteria have several layers of peptidoglycan, a material made of sugars and amino acids, in their cell wall, whereas gram-negative bacteria have only one peptidoglycan layer. There are various types of enteric bacteria that can be further classified according to their cell wall type and shape. ... green and orange candy
