 The study aimed to investigate the potential of biocontrol agents to protect Egyptian stone monuments from deterioration, caused by fungi and bacteria. The researchers isolated and identified three fungal and one bacterial strain from the temple of Athar in Luxa, Egypt. They also studied the effects of these organisms on the health of human cells and found them to be nantarxic. Additionally, they analyzed the metabolites produced by the Streptomyces exfoliator Samar 2021 strain and found it to have strong antifungal and antibacterial properties. Furthermore, they conducted gas chromatography analysis to identify the compounds present in the metabolites and found 13 different compounds. Finally, they applied the metabolites to stone monuments and observed no changes in color or texture. Overall, this study suggests that biocontrol agents could be a promising alternative to chemical treatments for preserving Egyptian monuments. This article was authored by Bosma T.
