Summary

This research explores how fungi can help combat antibiotic resistance, which is becoming a major global health threat. Scientists are investigating fungi’s ability to produce new antibiotics that could fight resistant bacteria. The study shows that fungi have enormous potential for creating new medicines, especially using modern technology and improved cultivation methods. Impacts on everyday life: • New antibiotics from fungi could help treat infections that current medicines can’t cure • Better understanding of fungi could lead to more affordable and effective medications • Improved production methods could make life-saving drugs more widely available • Natural compounds from fungi might have fewer side effects than synthetic drugs • Research advances could help prevent future antibiotic resistance crises

Background

Antibiotics are essential in modern medicine for treating infectious diseases. However, their extensive use and misuse, combined with bacterial adaptability, has led to dangerous increases in multi-drug-resistant (MDR) bacteria. Recent antibiotics entering the market have similar modes of action to existing ones, allowing bacteria to quickly develop resistance. This makes treating infections increasingly challenging, especially when MDR bacteria form biofilms.

Objective

This study aims to review the bioprospection of fungi to produce new drugs to address the growing problem of MDR bacteria and biofilm-associated infections. The research explores how filamentous fungi, with their large and largely unexplored secondary metabolome, can be potential sources of novel antimicrobial compounds.

Results

The review found that filamentous fungi have significant potential for producing novel antimicrobial compounds. Various cultivation techniques and optimization strategies can enhance metabolite production. New technologies in genomics, transcriptomics, proteomics, metabolomics, and localizomics, combined with proper identification of biochemical pathways, are key to inducing or inhibiting secondary metabolite expression. The study identified multiple successful examples of antibiotic production from fungi, including both traditional and novel compounds.

Conclusion

Fungi have significant potential to address antibiotic resistance challenges through their diverse secondary metabolome, which is now more accessible with recent advancements in genomics, metabolomics, and cultivation techniques. Natural products from fungi have regained relevance in drug discovery due to improved screening techniques. The future looks promising as new fungal species are identified and computational power increases, allowing for more accurate predictions in metabolite production and discovery.
