Luminescent Microbial Bioassays and Microalgal Biosensors as Tools for Environmental Toxicity Evaluation

Abstract: This chapter deals with toxicity bioassays and biosensors based on luminescent microorganisms that report on global toxicity of a sample in such a way that luminescence is reduced or inhibited in the presence of toxic compounds that impair metabolism. Both natural and recombinant microorganisms are considered. A detailed description of their main characteristics and environmental applications is reported. Bioassays for detecting oxidative stress (both bioluminescent and fluorescent bioreporters) are also menti… Show more

“…The metabolic inhibition-based bioluminescence bacterial biosensors have been developed and utilized in several pollutants detection [ 74 ]. Different signaling elements producing bioluminescence such as luciferase were used in the construction of bacterial biosensor, or naturally presented in bacteria that could be directly used in sensing [ 74 ]. The luciferase genes from bacteria and firefly have been suggested to be highly sensitive and broadly used as a reporter gene.…”

“…The bioluminescence would diminish in the presence of environmental pollutants due to the inhibited bioluminescence reaction. The ATP-dependent bioluminescence could be used in developing the metabolic inhibition-based biosensors for it can reflect the ATP decrease caused by environmental toxicants [ 67 , 74 ]. On the other hand, the energy-consuming lux operon reaction in Vibro spp.…”
