THE IMPACT OF DOPE COPPER OXIDE IN REDUCING PATHOGENIC MICROORGANISMS IN CONTAMINATED WATER A CASE STUDY OF CANDIDA, PENICILLIUM AND ASPERGILLUS niger

Abstract

Water contamination poses a severe threat to public health and the environment, necessitating innovative approaches for its remediation. This study investigates the effectiveness of 0%, 1%, 3% and 6%. Manganese-doped copper oxide (0%, 1%,3% and 6% Mn doped-CuO) nanoparticles in removing fungi contaminants from water. The contaminants of focus are Aspergillus niger, Candida and Penicillum. The nanoparticles were synthesized using chemical co-precipation method and characterized for their physicochemical properties with the use of FTIR,SEM and XRD. The effectiveness of the synthesized, was carried out using microbial analysis and turbidimetry.The results obtained revealed that microbial potency of manganese – doped copper oxide nanoparticle against Aspergillus niger, Candida and Penicillum. Among the various nanoparticle formulation studied, optimal inhibition was obtained at 1% doping and 80mg concentration for Candida, at 0% doping and 40mg concentration for Aspergillus and at 3% doping and 20mg concentration for Penicillum. However, as doping levels increase beyond the optimal range, there is a discernible decrease percentages, possibly indicating a saturation effect or altered nanoparticle properties.
