Area of Science:

• Microbiology
• Natural Product Chemistry
• Drug Discovery

Background:

• Myxobacteria are Gram-negative soil bacteria known for complex life cycles and secondary metabolite production.
• Antibiotic resistance necessitates exploring natural sources for novel antimicrobial agents.
• Myxobacteria produce diverse bioactive compounds via polyketide synthases (PKSs) and non-ribosomal peptide synthases (NRPSs).

Purpose of the Study:

• To investigate Myxobacteria as a source of new antibiotics against resistant pathogens.
• To functionally characterize Myxobacterial species for their bioactive compound production.
• To assess the efficacy of Myxobacterial compounds against various infectious disease agents.

Main Methods:

• Culturing and functional characterization of Myxobacterial species.
• Analysis of secondary metabolites, including PKS and NRPS derivatives.
• Testing bioactivity against a spectrum of bacterial, fungal, and other pathogens.

Main Results:
