Microbial attack, particularly fungal degradation of cellulose, is a leading cause paper damage. To address spores and the rising concern microbial drug resistance, nano-Germanium dioxide (GeO2)/cetyltrimethylammonium bromide (CTAB) complex (nano-GeO2/CTAB complex) with potent antibacterial properties was synthesized. Its inhibitory effects were evaluated against bacteria, including Gram-positive Staphylococcus aureus Gram-negative Escherichia coli, as well fungi isolated from (Fusarium spp., Aspergillus Penicillium citrinum). The nano-GeO2/CTAB exhibited significant (p < 0.05) S. E. coli. Moreover, 60 min treatment 1 mg/mL significantly inhibited growth all tested reduced their biomass after five days culture, while 4 completely deactivated spores. Filter pre-treated showed complete resistance to exhibiting no clear inhibition zone devoid bacterial growth. In contrast, untreated controls displayed coverage exceeding 95% within days. These findings highlight promising antimicrobial agent for protecting materials degradation.
