Bacterial Deterioration in the Limestone Minaret of Prince Muhammad and Suggested Treatment Methods, Akhmim, Egypt

El-Amir Muhammad’s minaret in Akhmim, Sohag, Egypt, is constructed of limestone and has been exposed to many factors damage as a result the high levels ground water. Limestone strongly affected by water, especially when being impure. The current work discusses results analytical techniques including chemical testing determine types soluble salts through optical microscopy, electronic scanning electron microscope with an X-ray energy dispersion system (ESEM) study causes rapid degradation. Microbial weathering phenomena toward were also studied. Different bacteria fungi isolated from outdoors indoors air building which Bacillus cereus OK447647, B. subtilis OK447648, Serratia marcescens OK447650, Pseudomonasoryzihabitans OK447649, Aspergillus flavus, A. niger, Penicillium chrysogenum Cladosporium cladosporoids most representative. OK447647 OK447648 have shown ability for calcium carbonate dissolving. minimal inhibitory concentrations (MICs) sodium azide investigated against growth microbial isolates. Sodium at 100 ppm was found be best treatment bacterial isolates although it had no significant effect fungi.
