Bioremediation of copper-contaminated soils by bacteria
Although copper (Cu) is an essential micronutrient for all living organisms, it can be toxic at low concentrations. Its beneficial effects are therefore only observed for a narrow range of concentrations. Anth...

Optimisation of the cell release from immobilised cells of Bacillus simplex cultivated in culture media enriched with Cd2+: influence of Cd2+, inoculum size, culture medium and alginate beads characteristics
Calcium alginate beads were used to entrap a Bacillus sp. that has the ability to biosorb cadmium. During the batch incubation of alginate beads in a `rich' or a `poor' liquid medium, cell release out of the bead...

Fermentation of D-xylose by free and immobilized Saccharomyces cerevisiae
With D-xylose (50 g l ) as sole carbon substrate, aerobic cultures of S. cerevisiae consumed significant amounts of sugar (26.4 g l ), producing 4.0 g xylitol l but no ethanol. In the presence of a mixture of ...
