“…The absorption peaks at 910 cm -1 and 861 cm -1 in the EPS produced by C. rugosa and absorption peaks at 912 cm -1 and 875 cm -1 in C. laurentii exopolysaccharide revealed the coexistence of α and β glycosidic bonds [34]. Similar FT-IR results were reported by Ma et al [35]. …”

BackgroundPresent study deals with the removal of Zn(II) ions from effluent using yeast biofilm formed on gravels.MethodsThe biofilm forming ability of Candida rugosa and Cryptococcus laurentii was evaluated using XTT (2,3-bis[2-methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxanilide) reduction assay and monitored by scanning electron microscopy (SEM), and Confocal laser scanning microscopy (CLSM). Copious amount of extracellular polymeric substances (EPS) produced by yeast species was quantified and characterized by Fourier transform infrared spectroscopy (FT-IR).ResultsYeast biofilm formed on gravels by C. rugosa and C. laurentii showed 88% and 74.2% removal of Zn(II) ions respectively in batch mode. In column mode, removal of Zn(II) ions from real effluent was found to be 95.29% by C. rugosa biofilm formed on gravels.ConclusionThe results of the present study showed that there is a scope to develop a cost effective method for the efficient removal of Zn(II) from effluent using gravels coated with yeast biofilm.

Metal bioremediation was studied by biosorption of analytical grade copper Cu(II) and silver Ag(I) by an exopolysaccharide (EPS) produced by marine bacteria from French Polynesia. Colorimetric analysis showed that EPS was composed of neutral sugars, uronic acids, acetate and especially high sulfate amount (29%). Metal biosorption experiments were conducted in batch process. Results showed that the maximum sorption capacities calculated according to Langmuir model were 400 mg g−1 EPS (6.29 mmol g−1) and 256 mg g ) for Cu(II) and Ag(I), respectively. The influence of pH, biosorbent concentration, ionic strength on EPS biosorption capacities was investigated.Results showed that bacterial EPS can be considered as very promising for copper and silver bioremediation. Further development in dynamic and continuous process at the industrial scale will be organized next.
