Farmers are highly dependent upon agrochemicals to boost crop production through soil fertilization and and insect pests, pathogens, parasites, and weeds management . However, contentious application of agrochemicals on the farm has aggravated residual accumulation and has become problematic for environmental safety besides causing disease to humans and other animals. Thus, the analysis of chemical residues from the environment is vital for policymakers and communities. Mostly, chemists were devoted to analyzing the existing contaminants from different sources by using highly sophisticated chromatographic equipment, although it is time taking, laborious, costly, and that required well-trained professionals. However, biosensors are more important to analyze chemical contaminants from different samples using various bioreporters integrated with electrochemical and optical transducers. Microbes are metabolically diverse, amenable for genetic engineering, cost effective in culturing, and tolerant to diverse conditions. Thus, microbial biosensor is capturing attention and becoming more effective for environmental monitoring. Therefore, this review assessed the implication of microbial biosensors for pesticide detection and the role of genetic engineering for strain improvement.

作为农药检测器的微生物生物传感器：概述

农民高度依赖农用化学品，通过土壤施肥和害虫、病原体、寄生虫和杂草管理来提高作物产量。然而，农用化学品在农场上的争议性应用加剧了残留积累，除了对人类和其他动物造成疾病外，还对环境安全造成了问题。因此，分析环境中的化学残留物对决策者和社区至关重要。大多数情况下，化学家致力于使用高度复杂的色谱设备分析来自不同来源的现有污染物，尽管这既费时又费力，成本高，并且需要训练有素的专业人员。然而，生物传感器对于使用与电化学和光学传感器集成的各种生物报告器分析来自不同样品的化学污染物更为重要。微生物在代谢上是多样的，适合进行基因工程，在培养方面具有成本效益，并且能够耐受各种条件。因此，微生物生物传感器正在引起人们的注意并在环境监测方面变得更加有效。因此，本综述评估了微生物生物传感器在农药检测中的意义以及基因工程在菌株改良中的作用。
