Chemical sterilization using hydrogen peroxide (H₂O₂) and chlorine dioxide (ClO₂) was assessed as an alternative to traditional steam sterilization for preparing mushroom substrates. Both agents achieved a microbial reduction of ≥6 log, while maintaining biological efficiency comparable to autoclaving, even at low concentrations. These methods offer several advantages, including low energy consumption, simple setup, and cost-effectiveness, making them suitable for small-scale farms. However, there are concerns regarding species-specific sensitivity and potential residue risks. A life cycle assessment (LCA) indicated that chemical sterilization results in a lower environmental impact compared to thermal methods. Overall, H2O2 and ClO2 are promising options for decentralized and sustainable mushroom cultivation.
