After Gram, researchers can identify gram-positive bacteria, more precisely by additional testing. They can explore, such as morphology of unknown bacteria, structure, movement and genetics. Previous studies have divided order strattera the gram-positive bacteria in four families --- Bacillaceae, Micrococcaceae, Mycobacteriaceae and Peptococcaceae --- and each of these families have control characteristics:
Bacillaceae bacillary bacteria. If they can move themselves, they have flagella covering the entire surface. Micrococcaceae have a circle. They can not move by themselves and when they fall, they form groups of fours, or tetrady. Mycobacteriaceae are shaped slightly curved rods. When they fall, they can either form a long branch or crossing the form. Peptococcaceae as circle-shaped. Due to their structure, they need an environment without oxygen, and some can not grow where there is salt. Considerable diversity exists within each family. .
