Thermophilic Fungal-Based Composting Accelerator to Enhance Phosphorus Cycling in Urban Organic Waste
Short Introductive summary
This study aimed to develop a composting accelerator based on the thermophilic fungus Myceliophthora thermophila I-1D3b using solid-state fermentation (SSF), focusing on enzymatic production. Six substrate formulations were evaluated: sugarcane bagasse and wheat bran (7:3), sugarcane bagasse and soybean meal (0.43:9.57), tree pruning residues and wheat bran (7:3), fruit residues, fruit residues with 20% sawdust, and rice. Substrates were adjusted to 60–75% moisture, sterilized (121 °C, 40 min), inoculated and incubated at 45 °C for 120 h. Enzymatic activities (phosphatase, amylase, endoglucanase, protease, lipase and chitinase) were quantified by spectrophotometric methods. The effects of substrate composition and cultivation conditions, including gas exchange, were assessed. Lignocellulosic materials combined with nutrient-rich substrates provided optimal conditions. The results support the development of a bio-based composting accelerator capable of enhancing organic matter degradation and phosphorus availability. This approach contributes to waste valorisation and nutrient recovery and may be integrated into biorefinery strategies for sustainable resource management.
