WebBacterial Classification. Bacteria are classified according to their shape. The two main groups of bacteria are cocci (spherical-shaped) and bacilli (rod-shaped) (Brooker 2008). These two groups are then subdivided into gram-positive and gram-negative bacteria. (Gram was the microbiologist who devised the staining method.) Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane.
