Abstract Even though raw mass spectrometry data is information rich, the vast majority of underutilized. The ability to interrogate these rich datasets handicapped by limited capability and flexibility existing software. We introduce Mass Spec Query Language (MassQL) that addresses issues enabling an expressive set patterns be queried directly from data. MassQL open-source query language for flexible spectrometer manufacturer-independent mining MS envision flexibility, scalability, ease use...
Bacteria have evolved various strategies to combat heavy metal stress, including the secretion of small molecules, known as metallophores. These molecules hold a potential role in mitigation toxic contamination from environment (bioremediation). Herein, we employed combined comparative metabolomic and genomic analyses study metallophores excreted by Delftia lacustris DSM 21246. LCMS-metabolomic analysis this bacterium cultured under iron limitation led suite lipophilic exclusively secreted...
Soft corals distributed across the Red Sea coasts are a rich source of diverse and bioactive natural products. Chemical probing soft coral Litophyton arboreum led to isolation structural characterization an undescribed sesquiterpenoid, litoarbolide A (1), along with 14 previously reported metabolites (2-15). The chemical structures isolates were assigned based on NMR as well high resolution electrospray ionization mass spectrometry (HR-ESI-MS) data. Litoarbolide is supposed be biosynthetic...
Glycyrrhiza inflata Batalin is among the three glycyrrhizin producing species and can be distinguished from other with regard to its retrochalcone contents. Seven retrochalcones, echinatin licochalcones A, C, D, E, K, L were isolated characterized chloroform extract of G. roots. Among isolates, licochalcone was found previously undescribed. Structure elucidation these specialised metabolites achieved through NMR mass spectroscopic data analyses.
Cupriavidus necator H16 is known to be a rich source of linear lipopeptide siderophores when grown under iron-depleted conditions; prior literature termed these compounds cupriachelins. These small molecules bear β -hydroxyaspartate moieties that contribute photoreduction iron bound as ferric cupriachelin. Here, we present structural assignment cupriachelins from C. B-4383 limitation. The characterization based on MS/MS fragmentation analysis, which was confirmed by 1D- and 2D-NMR for the...
Four undescribed cembranoids, sarcoroseolides A-D (1-4) along with nine reported related cembranoids (5-13) were isolated from the soft coral Sarcophyton roseum. The chemical structures of elucidated by extensive 1 D and 2 NMR as well HR-ESIMS spectroscopic data. Moreover, geometric absolute configurations assigned modified Mosher's method and/or NOESY experiments. extract metabolites evaluated for their potential anti-inflammatory cytotoxic activities.
Extracting DNA from cyanobacteria can be a challenge because of their diverse morphologies, challenging cellular structure, and the heterotrophic microbiome often present within cyanobacterial cultures. As such, even when our yields are sufficient for sequencing, percentage reads coming host low, leading to incomplete genomes spread across several scaffolds. In this research, we optimized isolation protocol using three iterative cell lysis steps enrich portion isolated rather than...
Bacteria have evolved numerous mechanisms to resist metal toxicity, including small-molecule chelators (metallophores). This study presents a dual screening methodology isolate metallophore-producing bacteria from the Carpenter Snow Creek Mining District for potential use in heavy-metal bioremediation. Soil samples were screened on metal-supplemented plates which colonies picked onto chrome azurol S (CAS)-dyed plates. Copper or cerium toxicity was used as primary selection step, while CAS...
