A New Extremotolerant Ecotype of the Fungus Pseudotaeniolina globosa Isolated from Djoser Pyramid, Memphis Necropolis, Egypt.

ABSTRACT: Most of the rock-inhabiting fungi are meristematic and melanized microorganisms often associated with monument biodeterioration. In previous microbial profiling of the Egyptian Djoser pyramid, a Pseudotaeniolina globosa isolate was found. The current study aimed to characterize the P. globosa isolated from the Djoser pyramid compared with an Italian isolate at morphological, physiological, and molecular levels. Experiments were carried out to test temperature, salinity, and pH preferences, as well as stress tolerance to UV radiation and high temperature, in addition to a multi-locus genotyping using ITS, nrSSU or 18S, nrLSU or 28S, BT2, and RPB2 markers. Morphological and molecular data confirmed the con-specificity of the two isolates. However, the Egyptian isolate showed a wider range of
