Optimal time for AgNPs synthesis: AgNPs solutions were synthesized under the optimal conditions at 28 °C in the dark, Ag+ concentration is 10 mM, and adjust the pH of HX-YS treated AgNPs solutions to 6.0, LPP-12Y is 5.0; OD value was determined everyday at the maximum absorption wavelength of AgNPs: the maximum absorption wavelength of AgNPs solutions treated with HX-YS fermentation broth is 450 nm, while LPP-12Y is 430 nm [(a) solutions are treated with HX-YS; (b) solutions are treated with LPP-12].
