Abstract
Biodegradation of estrogen hormone micropollutants is a pervasive approach towards their remediation. Fluorescently labelled substrates are used extensively for rapid, near real-time analysis of biological processes and are a potential tool for studying biodegradation processes faster and more efficiently than conventional approaches. However, it is important to understand how the fluorescently tagged surrogates compare with the natural substrate in terms of chemical analysis and the intended application. We derivatized three natural estrogens with BODIPY fluorophores by azide-alkyne cycloaddition click reaction and developed an analytical workflow based on simple liquid-liquid extraction and HPLC-PDA analysis. The developed methods allow for concurrent analysis of both fluorescent and natural estrogens with comparable recovery, accuracy, and precision. We then evaluated the suitability of BODIPY-labelled estrogens as surrogate substrates for studying biodegradation using a model bacterium for estrogen metabolism. In service of this objective, the developed analytical methods were successfully employed to assess the biological transformation of 17β-estradiol, with and without BODIPY fluorescent tag.
