Microbial Community Restructuring Enhances Composting Efficiency: Synergistic Roles of Thermal Cycling and Fungal Inoculants (Fomes lignosus and Penicillium glabrum) in Metabolic Adaptation.

ABSTRACT: This study demonstrates that synergistic integration of thermal cycling (28°C-58°C) and fungal inoculants (Fomes lignosus, Penicillium glabrum) enhances humification in cattle manure composting by restructuring microbial communities toward metabolic adaptation. Through a temperature-phased aerobic system, both inoculants significantly improved carbon conversion efficiency, with F. lignosus (B) and P. glabrum (G) increasing total organic matter by 4.71% and 3.42% (vs. control), humic acid content by 4.58-fold and 2.35-fold, and FDA hydrolase activity by 3.28-fold and 1.22-fold, respectively, confirming improved humification and nutrient cycling. Temperature-inoculant synergy drove functional differentiation. Respiratory profiling revealed that P. glabrum enhanced oxygen consumption by 1.3-f
