Crystal Growth and Kinetic Behaviour of Pseudoalteromonas espejiana Assisted Biosynthesized Gold Nanoparticles

Influence of various substrate concentration (HAuCl₄) on AuNPs biosynthesis kinetics based on ICP-OES analysis. It was observed that the production of AuNPs is directly proportional to the substrate concentration hence the highest production occurred at 10 mg/L. The enzyme: substrate ratio was 2 : 3, the pH was kept at 9 and temperature at 30°C throughout the reaction with 150 rpm agitation.
