Estimating the term…
The present invention relates to the field of nanotechnology, more specifically to the manufacture or treatment of nanostructures, and in particular provides arsenic sulfide nanostructures, as well as a process for obtaining nanostructures of arsenic sulfide. The present invention provides a process for obtaining arsenic sulfide (As—S) nanostructures from a microorganism, which comprises the steps of culturing under appropriate conditions the strain Fusibacter ascotence in the presence of a source of sulfur and a source of arsenic; and recovering arsenic sulfide nanostructures (As—S) from the precipitate obtained from said culture. The present invention provides, also, a nanostructure of arsenic sulfide which is a nanowire having a monoclinic crystal structure. The present invention further provides a nanostructure of arsenic sulfide, which is a nanoparticle with a monoclinic crystal structure.
A process for obtaining arsenic sulfide (As—S) nanostructures from a microorganism, comprising the steps of:
An arsenic sulfide nanostructure, which is a nanowire or a nanoparticle having a monoclinic crystal structure, and is obtained from the strain Fusibacter ascotence, deposited within the American Type Culture Collection under accession number ATCC BAA-2418.
