Abstract

KENI FINE® is a specialty nickel coating technology applicable to various materials. It discharges anti-bacterial species on the contact side by reacting with adsorbed water in air, and showed antibacterial properties. When suspensions of Pseudomonas aeruginosa, Salmonella typhimurium, and Staphylococcus aureus were placed on the KENI FINE® coated stainless steel, multiplication of these bacterias were inhibit on the KENI FINE® coated stainless steel. The germination of zoospores of Pythium aphanidermatum and micro conidia of Fusarium oxysporum was also inhibited on the KENI FINE® coated stainless steel, but uncoated stainless steel did not inhibit the germination of these fungus spores. These results indicated that KENI FINE® coating changed materials to antibacterial and antifungal materials. KENI FINE powder also inhibited the germination of zoospores of P. aphanidermatum and micro conidia of F. oxysporum. A rock wool cultural mat treated with a water soluble emulsion containing KENI FINE® powder inhibited algae growth on its surface. The suppressive effect of algae on the rock wool surface was reduced depending on the dilution rate of the water soluble emulsion containing KENI FINE® powder. However, decreased dilution of water soluble emulsion containing KENI FINE® inhibited lettuce growth. Lettuce growth was inhibited a little in the more diluted soluble emulsions such as when it was diluted 50 or 100 times. Cholosis did not appear in the more diluted soluble emulsion. KENI FINE® powder also showed antibacterial and anti algae properties.
