“…Entrapment in beads of calcium alginate gel is one of the most widely used techniques for immobilising bacteria (Scott et al, 1989), enzymes (Hussain et al, 1985), yeast (Bustard and McHale, 1997;Serp et al, 2000), algae (Crist et al,1994), animal cells (Lu et al, 2000). On the other hand, calcium alginate has been one of the most extensively investigated biopolymers for binding divalent heavy metals thus, it has been used for the removal of heavy metals from dilute aqueous solutions (Apel and Torma 1993;Araújo and Teixeira, 1997;Chen et al, 1997;Chen et al 1992;Ibañez and Umetsu, 2002;Jang et al, 1999;Lázaro et al, 2003;Veglio et al, 2002).…”

The average uranium concentration in algae within the direct surroundings of both tailings is higher than 20 mglkg dry matter, relatively independent from the variable concentration in the water in the range of some hundred J.lg/1.…”

Abstract. Algae including cyanobacteria function as efficient temporary sinks in wetlands below uranium mining tailings and dumps. As far as investigated their accumulation potential exceeds in parts higher plants and soils, microphytic and epiphytic algae each being superior to macrophytic algae and vascular plants. The enrichment compared to the surrounding water is high. In the living biomass uranium can be accumulated up to 300 mg/kg dry matter (DM), Iead up to 250 mg/kg DM and arsenic even up to 4000 mg!kg DM. On average approx. half of the contamination is loosely adsorbed on the cell surfaces. The dimension of contaminant remobilization is yet unknown. lntroductionHeavy metals and arsenic are -with few exceptions -very efficient accumulated in algae and aquatic plants (literature overview see Vymazal 1994). In photoautotrophic algae and cyanobacteria enrichment up to several percent per gram dry matter can be expected due to relatively high surface/volume ratio, mucilage (metal complexing) sheaths (e.g. Yen et al. 2001), fast growth rates and the ability to store phosphate actively as polyphosphate at growth Iimitation caused by the Iack of other resources (Vymazal 1994; Franklin et al. 2000). A P like behavior of As and interactions with Uranium are assumed (Planas and Healy 1978; change in chemical speciation: Knauer et al. 1999; Meinrath et al.l999; Mkandawire and Dudel, this volume ).The specific performance of photoautotrophic algae or chemoautotrophic bacteria has so far been sparsely considered in field investigations. However, concentration factors resp. transfer factors for uranium and especially for radium have been calculated already decades ago (for summary see Williams 1990). B. J. Merkel et al.

“…The treated molasses was then decanted into shake¯asks and subsequently inoculated (5%) with K. marxianus IMB3 as described above. The biomass used in these studies was recovered by centrifugation from distillery spent wash (Old Bushmill's Distillery Co. Ltd., Bushmills, Co. Antrim, Northern Ireland) and prepared as described previously [13]. Treatment of the molasses dilutions with the biomass (dry weight, 2 g/150 ml) was carried out essentially as described for the ion exchange resin except that the biomass were recovered from the molasses by centrifugation.…”

The use of high concentrations of molasses as a fermentation feed-stock for ethanol production is normally precluded by the presence of inhibitory compounds. Use of the thermotolerant, ethanol-producing yeast strain Kluyveromyces marxianus IMB3 in fermentations containing high concentrations of molasses resulted in suboptimal production of ethanol. The results suggested that this was caused by the presence of inhibitory materials rather than an intolerance to increased concentrations of ethanol. In the current study we describe the pretreatment of molasses preparations with either an Amberlite Ò monobed mixed ion-exchange resin or non-living microbial biomass from a local distillery. In the study molasses samples diluted to yield a ®nal sugar concentration of 160 g/l were used as the substrate. Control fermentations using the untreated molasses dilutions yielded a maximum ethanol concentration of 40 g/l, representing 49% of the maximum theoretical yield. Fermentations using molasses samples pre-treated with Amberlite Ò or non-living biomass yielded maximum ethanol concentrations of 58 and 54 g/l, representing 71 and 66% of the maximum theoretical yield, respectively. The results suggest that pretreatment brings about removal of toxic or inhibitory materials from the fermentation feed-stock and we believe that such pre-treatments, particularly using the less expensive non-living biomass preparations may ®nd a role in processes concerned with the commercial production of ethanol from molasses using this microorganism.
