a Conical flasks containing cell-free extract in aqueous solution of 10−3 M of AgNo3 for F. oxysporum and the beginning of the reaction (left flask) and after 72 h of reaction (right flask). Formation of AgNPs is detected by color change observation of reaction medium from colorless to yellowness or dark brown. b UV–vis absorbance spectroscopic analysis of the AgNps. c Transmission electron microscopic analysis of the AgNPs
