Method using fusarium venenatum 1281-2 to synthesize nano-silver

The invention discloses a method using fusarium venenatum 1281-2 to synthesize nano-silver, the method includes the following steps: after fermental cultivation of the fusarium venenatum 1281-2, mycelium is collected, a residual culture medium is removed by washing with deionized water, the mycelium is resuspended in sterile deionized water for culture, the culture liquid is filtered to remove the mycelium to obtain fusarium venenatum 1281-2 culture supernatant; the obtained fusarium venenatum 1281-2 culture supernatant is taken as a reaction matrix, and is added into a silver nitrate solution for reduction reaction, and a nano silver product is finally obtained by centrifugation, wherein the fusarium venenatum 1281-2 preservation number is CCTCC M2014658. The synthetic method is green and environmentally-friendly, and is a high efficiency and simple synthesis method.
