Used in environmental and soil science research to assess microbial activity and overall soil health by measuring the hydrolysis of fluorescein diacetate (FDA). This assay helps researchers evaluate the functional diversity of soil microbial communities, making it valuable in studies related to agriculture, bioremediation, and ecosystem monitoring. The kit provides a quantitative method to detect enzyme activity, which correlates with microbial biomass and metabolic function. It is commonly applied in experiments assessing the impact of pollutants, land use changes, or soil treatments on microbial processes. Due to its sensitivity and specificity, the FDA hydrolyzing enzyme assay supports high-throughput screening in laboratory and field studies.
