Fig. 2From: Extracellular biosynthesis, OVAT/statistical optimization, and characterization of silver nanoparticles (AgNPs) using Leclercia adecarboxylata THHM and its antimicrobial activityThe UV–visible spectra of AgNPs biosynthesized by S3 bacterial supernatant. The absorption of AgNPs was recorded after 48 h of incubation following the addition of 1 mM AgNO3 to the bacterial supernatant. The absorption spectrum of AgNPs exhibited a strong peak at 420 nmBack to article page
