Carotenoids as Bioreporter for Environmental Toxicants Assessment

Environmental pollution is a global crisis due to the anthropogenic activities. Conventional chemical analytical tools and biosensors are effective tools in environmental toxicant assessment. For whole cell biosensors, chlorophyll was a well-studied pigment as bioreporter for the presence of envir...
