Abstract

Four saprophytic bacterial and fungal species attacked the manuscript that dated back to 1251 AH at Al-Azhar library
in Cairo, Egypt were isolated. Based on the partial 16S rRNA gene sequence, the isolated bacteria were Acinetobacter
indicus and Exiguobacterium aurantiacum. The fungal species were Stachybotrys chartarum and Aspergillus flavus. Acacia nilotica fruit extraction exhibited considerable antimicrobial activity at different concentrations against the
isolated bacteria and fungi.
