Abstract:
We inject Bacillus stearothermophilus AZ11 into avermectins fermentation wastes, and perform compost ferment and avermectins degradation so as to compost maturity of manure. Results show that the Bacillus strain can increase the degradation of avermectin and decrease compost time significantly. The optimal experimental conditions are water content of the compost of 70%, AZ11 inoculation of 5‰, ventilation time of 5 min every 12 h, completion of composting process in 24 d. Avermectins degradation rate is then over 98.7%.
Key words: Bacillus stearothermophilus, fermentation wastes, compost, degradation
