“…Maximum removal of Zn(II) ion by yeast biofilm occurred at 90 mg/L. The increase in initial Zn concentration increased the driving force to overcome mass transfer resistance of metal ion between aqueous and solid phases [41]. In this study, Zn(II) removal efficiency of C. rugosa and C. laurentii biofilm was found to be 88% and 74.2% of 90 mg/L respectively.…”

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.

Aim: Localization of Cr(VI) removal activity in Candida tropicalis strain and the study of its Cr(VI) removal capacity in soil. Methods and Results: Candida tropicalis strain HE650140 showed a remarkable capacity to completely reduce 50 mg l À1 of Cr(VI) in 48 h under aerobic conditions; however, a small change in total content of chromium in the culture liquid was detected, which can be explained by the formation of Cr (III). Fractionation of the cells showed that chromium removal activity was present in both the cytoplasm and membrane. The bioaugmentation of Cr (VI)-contaminated soil microcosms by live and dead biomass showed that yeast inoculation diminishes phytoavailable chromium from soils, improving different growth parameters of clover. Conclusion:The Cr(VI) removal activity was found in both cytoplasmic and membrane fractions. Both live and dead biomass of C. tropicalis were capable to reduce Cr(VI) in the soil and limit the toxicity of this metal to clover seedlings. Significance and Impact of the Study: This study is one of the few documents that present the ability of dead yeast to limit phytoavailability of Cr(VI) from soil. This is of great significance in bioremediation of Cr(VI)-contaminated soil.

“…The small peak disappeared and a larger peak emerged on the right of the original large peak while volumes of small and large pore (width >180 nm) both increased for BOFS in Bio-BOFS. It had been reported that some divalent metal ions, such as Ca 2+ , could aggregate and enhance the granulation of microbes (Mahoney et al, 1987;Schmidt and Ahring, 1993;Yin et al, 2008). Through atomic force microscopy (AFM) (Fig.…”
