Penelitian ini mengevaluasi pengaruh mutasi acak akibat radiasi gamma pada Aspergillus niger FNCC 6114 terhadap produksi xilanase melalui fermentasi padat menggunakan dedak gandum. Tiga isolat (Wild type, Mutan 3.6, dan Mutan 3.7) dipurifikasi secara parsial dengan presipitasi amonium sulfat 80% dan dialisis, kemudian dikarakterisasi aktivitas enzimnya. Mutan 3.7 menghasilkan aktivitas tertinggi, baik pada ekstrak kasar (≈21.540 U/mL) maupun setelah purifikasi (≈2.988.825 U/mL), dengan aktivitas spesifik 9.510 U/mg protein. Karakterisasi menunjukkan kondisi optimum pada pH 4 (12.482 U/mL; 39.721 U/mg) dan suhu 60 °C (15.270 U/mL; 48.586 U/mg). SDS-PAGE menunjukkan pita protein target 20–40 kDa yang sesuai dengan xilanase GH10/GH11, dengan Mutan 3.7 memiliki pita non-target paling sedikit. Hasil ini menunjukkan Mutan 3.7 sebagai isolat terbaik untuk produksi xilanase menggunakan dedak gandum.</mods:abstract><mods:classification authority="lcc">570 Biologi, Ilmu Hayat</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2026-06-04</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS SAINS DAN TEKNOLOGI</mods:publisher></mods:originInfo><mods:genre>Thesis</mods:genre></mets:xmlData></mets:mdWrap></mets:dmdSec><mets:amdSec ID="TMD_eprint_78429"><mets:rightsMD ID="rights_eprint_78429_mods"><mets:mdWrap MDTYPE="MODS"><mets:xmlData><mods:useAndReproduction>
