Identification of Bacteria
... The differences among bacteria are used to classify them and to identify a species. Bacteria come in a number of shapes. Most, however, are cocci (round), bacilli (rod-shaped), or spirilla (spirals). The way these individual cells are arranged is also variable among bacterial species. Although some ...

Quorum sensing

Quorum sensing is a system of stimulae and response correlated to population density. Many species of bacteria use quorum sensing to coordinate gene expression according to the density of their local population. In similar fashion, some social insects use quorum sensing to determine where to nest. In addition to its function in biological systems, quorum sensing has several useful applications for computing and robotics.Quorum sensing can function as a decision-making process in any decentralized system, as long as individual components have: (a) a means of assessing the number of other components they interact with and (b) a standard response once a threshold number of components is detected.
