introduction: antibiotics have the potential to adversely affect the microbial community. for anaerobic digestion, a sufficient methanogenic population needs to be preserved in the system. the main aim of this study was determination of inhibitory concentration of oxytetracycline on methanogenic bacteria. methods: a 120 ml jacketed bioreactor with a 90 ml working volume was inoculated granular ...
Degrading antibiotics discharged in the livestock manure in a well-controlled bioprocess contributes to a more sustainable and environment-friendly livestock breeding. Although most antibiotics remain stable during manure storage, anaerobic digestion can degrade and remove them to various extents depending on the concentration and class of antibiotic, bioreactor operating conditions, type of fe...
background: leachatecontaining high levels of organic pollution with ammonia, halogenatedhydrocarbons, heavy metals and inorganic salts. among the various methods fortreating leachate, has been developed membrane processes so that a morebiological process of membrane processes is used for separation of solid -liquid. the aimof this study was to evaluate the efficiency of membrane bioreactor eff...
Free-living amoebae pose a potential health risk in water systems as they may be pathogenic and harbor potential pathogenic bacteria known as amoebae resistant bacteria. Free-living amoebae were observed in 150 (87.2%) of the environmental water samples. In particular, Acanthamoeba sp. was identified in 22 (12.8%) using amoebal enrichment and confirmed by molecular analysis. FLA were isolated i...
Objective To explore the process of refuse decomposition in hybrid bioreactor landfill. Methods The bioreactor landfill was operated in sequencing of facultative-anaerobic and aerobic conditions with leachate recirculation. pH, COD, and ammonia in the leachate and pH, biodegradable organic matter (BDM), and cation exchange capacity (CEC) in refuse were detected. Results CEC increased gradually ...
