This study was performed to elucidate substrate specificity to the locust bean gum galactomannan by Trichoderma harzianum β-mannanase. The medium composition for enzyme production were determined 3% cellulose, 3% corn steep liquor, 1% KH₂PO₄, 0.2% (NH₄)₂SO₄, and incubated for 115 hr at 28℃. The β-mannanase exhibited maximum activity at pH 4.5 and 60℃. Locust bean gum galactomannan was hydrolyzed by the β-mannanase, and then hydrolysates separated by activated carbon column chromatography.
