EXTRACTION OF BIO-NANOMATERIALS FROM FUNGI ISOLATED FROM THE ARCHAEOLOGICAL BUSHEL FOR THE TREATMENT OF MICROBIAL INFECTIONS

The research paper aims to isolate and resist fungi as they are one of the factors of microbial damage to the archaeological bushel. The archaeological bushel understudy dates back to the era of King Farouk. It was one of the measuring tools that have been used for decades in measuring grains, especially wheat. The study helped identify the signs of damage because the bushel was extracted from a moist environment and was covered by clay calcifications and salts. There were morphological changes on the surface of the archaeological bushel, so the biological activities of the isolated microorganisms were investigated and the causative microorganisms from the archaeological bushel were isolated and characterized as Aspergillus flavus and Aspergillus fumigatus. Nanomaterials were created for the sterilization process of surfaces. Nano-silver and nano-gold materials were extracted from identified fungi and a comparison was made between them to choose the best in the treatment process. It was found that nano-gold 1% concentration is sufficient to inhibit all isolated microorganisms.
