Abstract:
Large amount of pharmaceutical waste will be produced during abamectin production. Existence of pesticide residue greatly restricts resource utilization of pharmaceutical waste. We isolated a strain AZ11 from those long-term stacked pharmaceutical waste, which had better abamectin degradation function. It was identified as Bacillus stearothermophilus through 16s rDNA sequence analysis. Experimental results show that the degradation rate can reach 77.6% after 72 hours of culture. The strain can grow better at temperature higher than 40 ℃. It demonstrates better protease and celluase activity. This indicates that the strain can implement resource and hazardfree utilization of pharmaceutical waste.
Key words: abamectin, pharmaceutical waste, Bacillus stearothermophilus, isolation, biodegradation
