Time course of specific metal removal (q), expressed as mg of metal removed per g of biomass dry weight, by Nostoc sp. N27P72 a and Nostoc sp. FB71 b cultivated in media culture containing (10 g/l) maltose, with copper, chromium, and nickel in single-metal solutions. Symbols represent the mean of at least three replicates and bars represent the standard error of the mean, if larger than the dimensions of the symbols, using one-way ANOVA (p < 0.05). Symbols indicate () for nickel, (-) for copper, and (▲) for chromium in the media
