... The total volume of the Earth’s oceans is 1.4 × 1018 m3 . The total number of bacteria is therefore 1012 bacteria m−3 × 1.4 × 1018 m3 = 1.4 × 1030 bacteria. What is the mass of a single bacterium? A typical bacterium is 1µm (10−6 m) in size or 1µm3 (10−18 m3 ) in volume. Being made mostly of water, ...

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.
