“…Advances in the field of environmental microbiology and biotechnology indicate that bacteria (Ahmad et al, 2010;Cheung and Gu, 1990;Congeevaram et al, 2007;Dermou et al, 2005;Gadd, 1990;Garbisu et al, 1998;Stasinakis et al, 2002;Zouboulis et al, 2004), fungi (Congeevaram et al, 2007;Kapoor and Viraraghavan, 1995;Sa, 2001;Sanghi and Sankararamakrishnan, 2009), yeast (Blackwell et al, 1995;Chen and Wang, 2007;Krauter et al, 1996), and algae (Bankar et al, 2009;Muñoz and Guieysse, 2006) either as pure or mixed cultures, can remove, chromium (VI) from aqueous solutions. Different species of Pseudomonas, Sporophyticus, Bacillus, Phanerochaete have been reported to be efficient chromium reducers (Desai et al, 2008;Gopalan and Veeramani, 1994;McLean and Beveridge, 2001;Molokwane et al, 2008;Pogaku and Kulkarni, 2006;Velásquez and Dussan, 2009;Zahoor and Rehman, 2009).…”
