Effects of Co-composting of Gentamicin Mycelia Residues with Different Auxiliaries on Gentamicin Residue, Enzyme Activity and Microbial Community Dynamics
摘要
This research aims to explore how incorporating various materials influences gentamicin residue, enzyme activity, and microbial populations during the composting of gentamicin mycelia residues (GMRs). In the study, rice chaff, corn cobs, mushroom residue, and peanut shells were added to GMRs in specific ratios for co-composting. The results showed that the addition of rice chaff, corn cobs and mushroom residue led to a rise in composting temperature, prolonged the thermophilic phase, and enhanced gentamicin degradation. The elevated temperatures also induced shifts in bacterial community composition and fostered greater diversity. Throughout composting, gentamicin suppressed the activities of cellulase, urease, phosphatase, and catalase.
