Abstract

A strain of Alcaligenes sp. Isolated from the sludge of industrial area was found to uptake 24.1 mg lead/g dried cell during incubation in medium containing 100g/ml of lead. Analyses of cellular subfractions reveal that fractions of cell wall contain 88.6 percent of lead found associated with the cells and the remainder is found associated with the cytoplasmic fraction. Ultrastructural examination of the cells cultured in media containing 500 and 1000g/ml of lead showed no major irregularities between cells of the treated and untreated cultures.
