Copper Uptake by Penicillium brevicompactum

Heavy metal biosorption sites in <i>Penicillium cyclopium</i>

“…The conditions for production of biomass have been described previously (Tsekova, K. et al 2001). The biomass, given from the stationary growth phase, was separated by filtration, washed with deionized distilled water and dried for 24 h at 60 º C. The dried biomass was powdered using a mortar and pestle.…”

“…All the sorption experiments were conducted twice and the average of two parallel experiments was used in the data analyses. The amount of heavy metal ions (mg or mmoles) biosorbed per g of biomass (q) was calculated as described previously (Ahmad et al, 2005;Tsekova et al, 2001).…”
