摘要: An indoor co-composting of gentamicin fermentation residues (GFR) and lovastatin (LFR) inoculated with gentamicin-degrading Aspergillus terreus FZC3 was conducted to remove residues. The results showed that treatment MFZC3, consisting a 10:1 blend GFR LFR (w/w), had the longest thermophilic phase (7days), quickest degradation (t½=4.4days), relatively higher percentage (96.7%) at end composting. Addition affected fungal diversity compost improved removal during composting 15:1 GFR:LFR blend. By analyzing variations community dynamics, it speculated could accelerate degradation. microbial dynamic were deeply by physicochemical properties, vice versa. In conclusion, be promising technology solve problem residue in waste.
