Adding value to by-products: Unraveling the complex structure of lignin with SIRIUS

Despite being one of Earth’s most abundant polymeric organic compounds, lignin is often considered a lower-value byproduct in industrial processes. Converting lignin into valuable chemicals or biomaterials requires a thorough structural characterisation of depolymerised products. This non-targeted analysis method involving 2D liquid chromatography and high-resolution tandem mass spectrometry uses SIRIUS in versatile ways to unravel the complex structures of depolymerized lignin.

Green silver: Unveiling the role of biomolecules in plant-based nanoparticle synthesis with SIRIUS

Metal nanoparticles from gold, silver, iron, copper, and others, range in size from 1 to 100 nanometers and have a broad variety of applications in computing, optics, cosmetics, food industry, medicine, and water treatment. Silver nanoparticles, known for their antimicrobial properties, are effective for remediating contaminated waters. Plant extracts are used as reducing agents for the environmentally friendly synthesis of silver nanoparticles. To improve this synthesis, identifying the biomolecules involved in the process is crucial. UHPLC-QTOF-MS and SIRIUS identified the key phenolic compounds involved in the silver reduction.

A liverwort under stress: compound classification with CANOPUS to detect metabolic shifts

Liverworts are chemically diverse plants with unique cell organelles responsible for the synthesis and storage of specialized metabolites. Untargeted metabolomics was used to analyze the metabolic stress response of liverworts without isolating individual metabolites. CANOPUS classified the affected compounds, and helped to map the biochemical pathways of the unique stress response of liverworts compared to vascular plants.
