HIGHLIGHTS
• Media type (broth, MSM, and water) influenced nucleation differing AuNP size.
• 60-70 nm range constituted the highest frequency of biosynthesized AuNPs at 23%.
• Dose-dependent inhibition of Enterococcus spp. strongest at 50 μg/mL AuNPs.
• AuNPs raised Degussa rate constant: 1.67 × under visible light, 2.5 × under sunlight.
