In all figures, the black triangles indicate the natural lead content of the cells. Cell numbers per ml rose from X 10" (day 0) to X 108 (day 7). The uptake during the first phase can be described by a Freundlich adsorption isotherm x/m -- k X c", where .r is the amount adsorbed, in, the mass of adsorbent, c, the concentration in solution, and k and n, the constants. The first equation can be rearranged to give a straight line in a log-log plot: log .v/m -- log k + (n X log c). TABLE I Pb concentration determined in medium, Platymonas subcordiformis, cultures.
