Abstract SCOBY disc is a unique structure of bacteria and fungi. It was pretty known in the mid Seventies in Egypt as “Tea fish”. To the author’s knowledge, no reports since then were published to use them in producing nanoparticles worldwide. The fascinating characteristics of its easily cultured, produce large amount of biomass, expected high enzymatic profile and nontoxic nature, made the SCOBY disc very interesting to challenge it to induce ecofriendly, highly efficient and stable gold nanoparticles. The addition of 1mM 0f gold trichloride hydrate (HAuCl4·3H2O) solution into the CFE of SCOBY disc grew on black tea medium, resulted in gold AuNPs at 25ºC (Au3+→Au0 ) momentarily. |
