“…The present study indicates the fail of the luffa adsorbed fugal biomass in removal of cadmium (II) from the waste water. Our results are supported by that reported by Gourdon et al (1990) and Iqbal et al (2007). This difference in the behavior depends on individual characteristics of each fungus and on different factors; the support may possesses poor mechanical stability as reported by Klooster and Lilly (1985).…”

“…The lower cobalt uptake at pH 2 has also been reported for A. nodosum, Porphyra tenera, Palmaria palmata, Chondrus crispus, M. pyrifera, Laminaria sp., and Sargassum natans [11]. The reduction in metal binding at low pH has also been reported in fungi [9] and in gram-positive and -negative bacteria [6]. It is well known that both the cell surface metal binding sites and the availability of metal in solution are affected by the pH.…”

“…In this experiment cell pellets of each culture harvested from a late log phase culture (60 h) was suspended in 1 M sodium azide (NaN 3 ) solution for 45 min to inhibit metabolic activity (Gourdon et al 1990). Cell suspensions were centrifuged then washed with the same processes as previously mentioned.…”
