The current study aimed to investigate the ability of Bacillus licheniformis isolated from the environment to synthesize gold nanoparticles (AuNPs). The study included isolating and identifying of B. licheniformis from the soil and investigating its ability to synthesis AuNPs, then identifying AuNPs using XRD, UV -vis., FeSEM, EDS, FTIR, and AFM. The results showed the ability of B. licheniformis isolated from soil to synthesis AuNPs by changing the color of the solution from yellow to ruby pink and the optical absorption using ultraviolet spectrometry showed the appearance of a beak of AuNPs at a wavelength of 530 nm. FeSEM electron microscopy showed that synthesized AuNPs were spherical in shape and homogeneous with a diameter ranging from 20.47 - 76.50 nm. Also, the results of XRD, FTIR, EDS, and AFM revealed the nanoscale properties of AuNPs synthesized from B. licheniformis.
