Metabolomics: Big Data Approaches

This chapter outlines the methodologies and applications of metabolomics in biotechnology. It details sample preparation – including quenching, cell disruption, and extraction – followed by detection and quantification using various chromatography-mass spectrometry techniques. The discussion then shifts to the application of metabolomics for identifying pathway bottlenecks and optimizing metabolic flux, where strategies such as isotopic labeling and advanced flux analysis provide insights into enzyme limitations and byproduct formation. Finally, the future directions emphasize the need for standardized protocols, automation, and robust database platforms to ensure consistency across large datasets and facilitate cross-laboratory comparisons. These advances are critical for enhancing the precision and utility of metabolomics in metabolic engineering and bioprocess optimization.
