Özet
The use of waste as a material that can be useful in other areas can reduce both waste generation and the need for resources. Welding powder with high heavy metal content should be used for other purposes. For this reason, the welding powder, which is frequently used in the metal industry and released after the welding process, is desired to be used as an agent against microorganisms in this study. Several biological activities of welding powder and its sintered forms also investigated. The welding powder and its sintered forms showed moderate antioxidant and antimicrobial activity. Welding powder without sintering is called WP. Welding powders sintered at 300 ?degrees C, 600?degrees C, and 900?degrees C are named as WP300, WP600, and WP900, respectively. DNA cleavage activity was tested, and it showed single-stand cleavage against pBR 322 plasmid DNA. They displayed excellent biofilm inhibition activity, and the biofilm inhibition of WP, WP300, WP600, and WP900 against S. aureus and P. aeruginosa were found as 99.34%, 99.21%, 98.99%, and 99.12% and 98.32%, 96.11%, 96.38%, and 95.39%, respectively, at concentrations of 500 mg/L, respectively. They also demonstrated significant cell viability activity against E. coli.
