Through the characterization of metabolic pathways, metabolomics is able to illuminate the activities of a cell at the functional level. However, the metabolome, which is comprised of hundreds of chemically diverse metabolites, is rather difficult to monitor. Mass spectrometry (MS)-based profiling methods are increasingly being utilized for this purpose. To this end, MS is often coupled to the separation techniques gas chromatography (GC), liquid chromatography (LC), and capillary electrophoresis (CE). The mass-based selectivity that the MS provides, together with the chromatographic or electrophoretic separation of analytes, creates hyphenated techniques that are ideally suited to the measurement of large numbers of metabolites from microbial extracts. In this chapter, we describe GC-MS, LC-MS, and CE-MS methods that are applicable to microbial metabolomics experiments.

Introduction: Gut microbiota alterations have been implicated in Autism Spectrum Disorder (ASD), yet the mechanisms linking these changes to ASD pathophysiology remain unclear.
Objectives: This study utilized a multi-omics approach to uncover mechanisms linking gut microbiota to ASD by examining microbial diversity, bacterial metaproteins, associated metabolic pathways and host proteome.
Methods: The gut microbiota of 30 children with severe ASD and 30 healthy controls was analyzed.

Background And Aims: Alcohol Use Disorder (AUD) is a psychiatric disorder characterized notably by gut microbial dysbiosis and insufficient dietary fiber intake. This study aims to investigate the effect of dietary fiber placebo-controlled intervention in patients suffering from AUD during a three-week period of alcohol withdrawal, in order to discover microbial-derived metabolites that could be involved in metabolic and behavioral status.
Methods: A randomized, double-blind, placebo-controlled study was performed with 50 AUD patients supplemented with inulin (prebiotic dietary fiber) or maltodextrin (placebo) during 17 days.

Neuropathic pain (NP) is a chronic disease state centred on neuroinflammation with a high prevalence and limited effective treatment options. Peroxisome proliferator-activated receptor α (PPARα) has emerged as a promising target for NP management due to its anti-inflammatory properties. Recent evidence highlights the critical role of the gut microbiome and its metabolites in NP pathogenesis.

This study investigated the effects of rumen-degradable starch (RDS) on lactation performance, gastrointestinal fermentation, and plasma metabolomics in dairy cows. Six mid-lactation cows, fitted with rumen, duodenum, and ileum cannulas, were used in a duplicated 3 × 3 Latin square design with 28-day periods. The cows were fed a low RDS (LRDS; 62.

The intestine features a two-front nutrient supply environment, comprising an enteral side enriched with microbial and dietary metabolites and a serosal side supplied by systemic nutrients, collectively supporting intestinal and systemic homeostasis, but there is currently no optimal approach for extracting and assessing the local intestinal microenvironment. Here, we present a protocol for constructing a nutrient supply model in mice and extracting gut interstitial fluid (GIF) via centrifugation. This model and the extracted GIF are suitable for downstream analyses.
