Microbial biosensors are compact, portable, cost effective, and simple to use, making them seem eminently suitable for the in situ monitoring of environmental pollution. One promising approach for such applications is the fusion of reporter genes with regulatory genes that are dose-dependently responsive to the target chemicals or physiological signals. Their biosensor capabilities, such as target range and sensitivity, could be improved by modification of regulatory genes. Recent uses of such genetically engineered microbial biosensors include the development of portable biosensor kits and high-throughput cell arrays on chips, optic fibers, or other platforms for on-site and on-line monitoring of environmental pollution. This mini-review discusses recent advances in microbial biosensors and their future prospects, with a focus on the development and application of genetically modified microbial biosensors for in situ environmental monitoring.

The aim of this multicenter study is to investigate risk factors for unplanned hospitalizations, including individual and environmental factors, notably air pollution.
The monitoring of the level of toxins, chemical pollutants, microbial contaminants, or other harmful substances in the environment or workplace by measuring the amounts of these toxicants in the bodies of people and animals in that environment, among other methods. It also includes the measurement of ENVIRONMENTAL EXPOSURE. Levels in humans and animals are used as indicators of toxic levels of undesirable chemicals.
Removal of ENVIRONMENTAL POLLUTANTS or contaminants for the general protection of the environment. This is accomplished by various chemical, biological, and bulk movement methods, in conjunction with ENVIRONMENTAL MONITORING.
The study of ENVIRONMENTAL POLLUTION and the toxic effects of ENVIRONMENTAL POLLUTANTS on the ECOSYSTEM. The term was coined by Truhaut in 1969.
The use of biological mechanisms, usually involving living organisms such as bacteria, for the reduction or regulation of the population of noxious, destructive, or dangerous pests. Environmental concerns have focused attention on natural forms of disease control as potentially safe and effective alternatives to chemical pesticides. This has led to increased efforts to develop control strategies that rely on natural predators and parasites or that involve genetically engineered microbial pest control agents.
