(Hwang et al 2008), Rhodococcus pyridinovorans PYJ-1 (Jung and Park 2005), Exophiala jeanselmei yeast (Cox et al 1997), Sporothrix variecibatus fungus (Rene et al 2010), or mixed bacteria cultures obtained from soil or activated sludge (Arnold et al 1997; Babaee et al 2010; Djeribi et al 2005; El Aalam et al 1993; Jorio et al 2000; Lu et al 2001; Novak et al 2008; Pol et al 1998). In the research, the maximum removal rates from 91 (Cox et al 1997) to 635 g m −3 h −1 (Ryu et al 2004) were obtained depending on the used microorganisms, bed load with pollution, and empty bed resistance time.…”
