Summary

Fungal fruiting bodies like mushrooms develop best within specific environmental ranges, including proper temperature (15-27°C), humidity (80-95%), light, and nutrients. This comprehensive review identifies the exact environmental ‘sweet spots’ where mushrooms thrive and explains the biotechnological applications of these fungi in medicine, food production, and environmental cleanup. The research provides practical guidance for commercial mushroom cultivation and discusses how genetic engineering could further improve production.

Background

Fruiting body development is a complex process involving multiple environmental factors, genetic regulation, and metabolic activities in fungal communities including ascomycetes and basidiomycetes. Recent advances in omics studies have provided insights into molecular mechanisms, but critical environmental optima that drive optimal fruiting body development remain largely unclear. Understanding these critical ranges is essential for informed decision-making in commercial fruiting body cultivation and sustainability.

Objective

This study synthesizes the critical environmental optima that drive optimum fungal fruiting body development in ascomycetes and basidiomycetes. It explores recent advances in fruiting body biotechnology and identifies emerging biotechnological prospects while addressing environmental complexity and uncertainties. The research aims to complement existing knowledge and provide evidence-based support for sustainable industrial biotechnology.

Results

The study identified critical environmental optima for fruiting body development: CO2 (15,000 ppm for spawning, 500-800 ppm for fruiting stage), humidity (80-95%), temperature (15-27°C with 25°C optimal), light (2000 lux or 200 μmol/m²/s), and pH (4.5-7.5). Operating below these critical optima is safer for fruiting body performance. Multiple biotechnological applications were identified including agriculture, medicine, bioactive compound production, and environmental sustainability across diverse fungal species.

Conclusion

Operating below critical environmental optima is safer for fruiting body development than exceeding them. Understanding these critical ranges is crucial for optimizing commercial cultivation and biotechnological applications. Future studies should emphasize omics-driven strain-substrate improvements and CRISPR-based genetic modifications to enhance precision cultivation and robust strain design for sustainable industrial biotechnology.
