Exploring the Role and Potential of Flow Cytometry in Advancing Environmental Research

Applied to a wide range of disciplines, including environmental science, clinical medicine, and cell biology, flow cytometry (FCM) is a critical analytical method that has revolutionized research through its speed, accuracy, and parameter versatility. The transformational power of FCM in environmental studies is its capacity to identify microbial cells regardless of cultivability, which has the potential to drastically change aquatic ecology and water treatment by facilitating in-the-moment, in-depth examinations of microbial communities. The principles of FCM allow for the detection of scattered and emitted light signals from individual cells, which makes it easier to identify and quantify different types of cells or particles inside samples. A flow cytometer’s electronic systems, optics, and fluidics are essential parts. The use of FCM extends to the investigation of DNA content and the creation of community profiles using single-cell forward scatter features. Non-metric multidimensional scaling (n-MDS), t-SNE, and SPADE are a few examples of visualization tools used in the interpretation of complicated community data. In addition, FCM is an effective and versatile technique in environmental science that greatly improves our understanding of ecological processes and human-caused effects on natural systems. Its ability to quickly analyse and quantify microorganisms in a variety of environmental matrices, such as soil, water, and sediments, makes it easier to monitor the health of the environment, identify pollution sources, and assess management strategies. In this chapter, we will look at the different approaches and advancements in FMC and how it continues to play a critical role in protecting ecosystems and laying out a sustainable future if environmental problems exist.
