Impact of Beta Cyclodextrin-Encapsulated Zinc Oxide Nanoparticles as Heterogeneous Catalysts in Microbial Oil Production: An Investigation

Abstract

The catalytic activity of beta cyclodextrin encapsulated zinc oxide (ZnO) nanoparticles in microbial oil synthesis was investigated utilizing Streptomyces fradiae as the microbe and rice washed waste water (RWW) as the fermentation medium.Zinc oxide nanoparticles introduced during fermentation influenced growth and production. When compared to control samples, the biomass percentage was 1.5 times higher, and the fatty acid profile was improved. The induction period (IP) investigation demonstrated that zinc oxide nanoparticles provided the highest oxidation stability up to 120 days of storage while also significantly reducing autoxidation. However, the inclusion of ZnO nanoparticles increased the cetane number and calorific value. A new study found that employing β-CD encapsulated ZnO nanoparticles in microbial oil production resulted in much higher production (63.5g/L) than the control sample (42.5g/L). As a result, these nanoparticles are predicted to be useful in energy-related applications.
