文摘

S. maltophilia SeITE02 is able to efficiently reduce toxic selenite to Se° nanoparticles. Thiol containing molecules are involved in the reduction of selenite to Se°. Biogenic SeNPs are covered by carbohydrates, lipids and proteins. SeNPs seeds are formed intracellularly and then released outside the cells.
