Screening for new metabolites from marine microorganisms

Area of Science:

• Marine biotechnology
• Natural product discovery
• Genomics and functional genomics

Background:

• Marine (micro)organisms are a promising source of novel metabolites with biotechnological potential.
• Advances in marine genomics and functional genomics (transcriptomics, proteomics, metabolomics) are revolutionizing metabolite screening.
• Limited but growing availability of marine microbial genome sequences aids discovery efforts.

Purpose of the Study:

• To provide an overview of current analysis techniques for screening and activity analysis of marine microbial metabolites.
• To highlight the application of functional genomics techniques for identifying bioactive compounds.
• To discuss recent high-throughput screening methods and novel approaches for metabolite discovery.

Main Methods:

• Genome sequencing of marine bacteria and algae.
• Functional genomics techniques: transcriptome, proteome, and metabolome analyses.
• High-resolution 2D-PAGE coupled with mass spectrometry for compound screening.
• Targeted analysis of antimicrobial compounds using proteomic or transcriptomic data.
• Review of recent high-throughput screening methodologies.

Main Results:

• Functional genomics, particularly transcriptomics, combined with advanced analytical techniques, enables effective screening for bioactive compounds.
• Proteome and transcriptome analyses are valuable for targeted discovery of specific compounds like antimicrobials.
