摘要：

In this paper, we report that selenium (Se) nanoparticles were first biosynthesized by Pseudomonas alcaliphila with a simple and eco-friendly biological method. The structural characteristics of Se nanopartides were examined. The results showed that spherical particles appeared with diameters ranging from 50 to 500 nm during incubation and Se nanorods were present after incubating in an aqueous reaction solution for 24 h. However, the formation of Se nanorods was interrupted when 5% (w/v) poly(vinyl pyrrolidone)(PVP)was added in the aqueous reaction solution, obtaining stable spherical Se nanoparticles with a diameter of about 200 nm.
