COPPER RESOURCES
Copper has been proven to inactivate some of the most common microbial contaminants found in crops. Some of those include:
Bacteria
- Klebsiella (bacteria)
- Carbapenem-resistant Enterobacteriaceae or CRE (bacteria)
- Acinetobacter baumannii (bacteria)
- Pseudomonas (bacteria)
- Enterobacter (bacteria)
- Escherichia coli O157:H7 (bacteria, AKA E. coli)
- Salmonella enterica (bacteria)
Molds (see articles on next page)
- Aspergillus (fungi)
- Fusarium (fungi)
- Penicillium (fungi)
Figure 1
Aspergillus niger spores after 7 days exposure on copper (C11000) (a) and aluminum (b); Aspergillus flavus after 4 days exposure on copper (c) and aluminum (d); and Aspergillus fumigatus after 4 days exposure on copper (e) and aluminum (f) assessed using epifluorescence microscopy. Spores or hyphae stained orange to red are metabolically active and those remaining green to yellow are not active.
