abstract：:A novel β-1,3-1,4-glucanase gene was identified in Bacillus sp. SJ-10 (KCCM 90078) isolated from jeotgal, a traditional Korean fermented fish. We analysed the β-1,3-1,4-glucanase gene sequence and examined the recombinant enzyme. The open reading frame of the gene encoded 244 amino acids. The sequence was not identica...
