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.
The inhibitory effects of erythromycin and streptomycin on methane production of anaerobic granular sludge treating avermectin wastewater were investigated. The results indicated that erythromycin and streptomycin showed different effects on methane production of the sludge sample. Obvious lag time, lower production rate and lower final production of methane as well as higher pH values in the presence of streptomycin indicated stronger inhibition of streptomycin on both acetogenesis and methanogenesis, compared to erythromycin. The low half-inhibitory concentration of streptomycin for methane production was obtained as 7.49 mg/L. Erythromycin showed complicated effect on methane production, not only inhibition, especially at low concentration. The maximum methane production rate and final methane production were obtained at erythromycin concentration of 10 mg/L and 120 mg/L, respectively. Different familiarities of antibiotics to microbes in the sludge were considered to be responsible for different effects on methane production.
