Leveraging Plant Transcriptomic Profiling to Unlock the Molecular Complexity Barrier for Green Sustainable Saponin Application in Oilfield Operations

Plant-derived saponins are a special type of amphiphilic glycosides that have emerged as a promising clean alternative to synthetic oilfield surfactants. Their broad-spectrum industrial applicability arises from their strong biochemical properties and eco-friendly nature. They have shown substantial experimental potential as oilfield surfactants for enhanced oil recovery and the remediation of oil-contaminated soils. With the growing demand for clean and sustainable oilfield chemicals, the focus has shifted toward plants as a source of sustainable saponin surfactants. Plants are virtually unlimited bioresources containing a vastly untapped reservoir of diverse and important compounds of industrial significance. However, low natural yields and the high molecular complexity of plant saponin biosynthesis pathways limit their potential for sustainable industrial applications. Transcriptomic profiling, an evolving biotechnological tool, provides omics-driven insights into key gaps in plant saponin biosynthesis pathways. Hence, we highlight the critical role of transcriptomic profiling in green chemistry and its transformative potential for the oilfield application of plant saponins. From plant genomics to oilfield chemistry via molecular biology for optimal and sustainable saponin production, we propose an effective strategy to maximize fossil fuel production while minimizing ecological concerns. This aligns with the Sustainable Development Goals and principles of a circular economy.
