The aim of the study was to explore
the biogenesis of nano-structures through reduction of selenium by soil
bacterium Pseudomonas aeruginosa. The strain under study indicated
tolerance of selenium upto 50 mg L-1, using reductive mechanisms
for detoxication, thus biotransforming selenium oxyanions to elemental
red selenium. Partial characterization using AFM of the biotransformed
selenium was carried out which indicated formation of spherical amorphous
allotropic elemental selenium.
