Characterization of Xylanase of Fungi Isolated from Janggyeong Panjeon in Haeinsa Temple

A study on the UNESCO-listed Haeinsa Temple's Janggyeong Panjeon, which houses ancient wooden Tripitaka Koreana blocks, identified five fungal species—Cladosporium cladosporioides, Penicillium citreonigrum, Penicillium toxicarium, Aspergillus versicolor, and Acremonium alternatum—that produce xylanase enzymes capable of degrading organic materials like cellulose, xylan, and lignin. These fungi thrive even at low temperatures (20°C) and in high humidity conditions (up to 80%), posing a risk to the cultural heritage site. Notably, xylanases from C. cladosporioides and P. toxicarium exhibited thermal stability under acidic conditions, while others showed lower thermostability. These findings suggest potential strategies for preserving organic cultural heritage by controlling microbial degradation, offering insights into conservation methods and biocontrol alternatives.
