SIRIUS on the body farm: Investigating microbial decomposers

Microbial decomposers break down human remains, recycling nutrients and influencing ecosystem dynamics. Is there a universal microbial decomposer network that assembles in response to mammalian remains? How does the network and the cadaver-derived nutrient pool change during the decomposition process and can this microbial community change be used for predicting time since death for forensic purposes?

Biotransformation of antibiotics in wastewater: A fungal solution investigated with SIRIUS

Antibiotics are crucial for fighting bacterial infections, but the rise of antibiotic resistance poses a serious threat to public health. Beyond healthcare, the presence of antibiotic residues in wastewater exacerbates the problem. Conventional treatment methods often fall short in adequately removing these compounds, perpetuating resistance. Biological processes, such as biotransformation by fungi, have emerged as promising alternatives. Researchers investigated the potential of fungi to transform antibiotics, using SIRIUS and CSI:FingerID to identify degradation products.

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.

Potential risk of impurities in pesticides: Elucidating structurally related impurities using ZODIAC

Thiacloprid is a first-generation, widely used, neonicotinoid insecticide. Its persistence in the environment and potential adverse effects on human health have raised significant concerns. Elucidating the impurity profile of pesticides is crucial for assessing their environmental impact and potential risks, and setting acceptable limits for impurities. Using enhanced molecular formula identification with ZODIAC, researchers demonstrate an approach for identifying structurally related impurities in pesticides.

Long-term storage in biobanks: Identifying unstable metabolites with CSI:FingerID and CANOPUS

Neonatal dried blood spots are not only important for newborn screening but also a powerful source for investigating the potential metabolic etiologies of various diseases using untargeted LC-MS-based metabolomics. So far it is unclear whether the metabolites in those samples remain stable in storage. CSI:FingerID and CANOPUS help to investigate the stability of metabolites and classes of molecules.
