Arsenic occurs naturally in the environment and also through agricultural and industrial pollution. Since arsenic species show different toxicities, it is important to be able to separate them. Methods using microorganisms are being applied increasingly to remove metal ions and different metal speci
The freshwater green alga, Chlorella vulgaris, was cultivated in a modified Detmer medium in the presence of arsenite in order to investigate tolerance, accumulation, transformation and excretion of arsenic species. When the alga was exposed to arsenite, arsenic accumulation markedly increased in th
Arsenic accumulated in living Chlorella vulgaris cells was solvent-fractionated with chloroform/ methanol (2: l), and the fractions were analyzed for arsenic. A large part of the accumulated arsenic was localized in the extract residues. The extract residue from the same extraction of C. vulgaris,
