Bacterial sensing circuits may be triggered by molecules originating from the environment (e.g., nutrients, chemoattractants). Bacteria also actively probe the environment for information, by releasing molecular probes to measure conditions beyond the cell surface -- telesensing. Perceiving the environment beyond is achieved by sensing environmentally induced changes in those probes, such as occurs when a siderophore chelates an iron atom, or a quorum sensing signal is inactivated by a specific enzyme or adsorbent. This information, captured by chemical and physical changes induced in specifically produced molecules transiting through the environment, enable bacteria to mount a contextually appropriate response.
