Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
A strain degradating pesticide efficiently was isolated from the soil was long-term pesticide-contaminated near the pesticide factory of Xiantao City, Hubei Province. It was named as HS-MP13 and characterized. The results indicated that the HS-MP13 strain was most similar to Bacillus cereus based on the results of morphologic characteristics, physiological and biochemical properties and phylogenic analysis of 16S rDNA sequence. The strain HS-MP13 was identified as B. cereus preliminarily. Under aerobic denitrification conditions, we have determined the degradation capacity for methyl parathion (MP) and denitrifying activity of HS-MP13 in the special medium with an initial concentration of 10 mM (140 mg/L) NO3--N and an initial concentration of 100 mg/L MP. The degradation rates of nitrates and MP within 12 hours were found to be 77% and 100%, respectively. It indicated that B. cereus was able to act simultaneously degradation of MP and denitrification under aerobic conditions and it may be a good candidate for aerobic wastewater treatment.
