A spring from a former copper shale mine in the area of Mansfelder Land, Germany, shows extremely high transition metal ion concentrations, i.e. 40mM Zn II , 208μM Cu II , 61μM As V , and 25μM Cd II . This makes it a challenging habitat for living organisms as they have to cope with metal ion concentrations that by far exceed the values usually observed in spring water...
Biochemical responses to cadmium (Cd2+) and copper (Cu2+) exposure were compared in two strains of the aquatic hyphomycete (AQH) Heliscus lugdunensis. One strain (H4-2-4) had been isolated from a heavy metal polluted site, the other (H8-2-1) from a moderately polluted habitat. Conidia of the two strains differed in shape and size. Intracellular accumulation of Cd2+ and Cu2+ was lower in H4-2-4 than...
The effect of cadmium (Cd) on fungal growth, Cd bioaccumulation and biosorption, and on the formation of potential heavy metal response indicators such as thiols, oxalate, and laccase was investigated in the white rot fungi Cerrena unicolor andAbortiporus biennis. Only the highest Cd concentration employed (200 μM) inhibited growth of C. unicolor, whereas already lower Cd concentrations caused decreasing...
