Therefore, nanoparticles could be the key factor for the future technologies. Scientific as well as public associations are paying their attention for nanoparticles technology as a good investment source. Nanoparticles could be produced via physical, chemical or biological methods (Haider and Kang, 2015; Ebrahiminezhad et al., 2017). Both chemical and physical methods use reducing agents such as sodium borohydride, sodium citrate and alcohols (Rai and Duran, 2011). However, using of microorganisms in synthesis of nanoparticles represents another great achievement because of the economic and ease production (Shelar and Chavan, 2014; Patel et al., 2015). Research revealed that biological methods is an inexpensive and eco-friendly way for synthesis of nanoparticles. This method used biological agents including bacteria, fungi, yeast and plants (Mourato et al., 2011). Recently, emerging such microorganisms as eco-friendly nano-factories to manufacture inorganic nanoparticles was attractive (Lee et al., 2004; Lengke et al., 2007).
