Prospects for Bio‐Industrial Application of an Extremely Alkaline Mannanase FromBacillus subtilissubsp.inaquosorumCSB31

Abstract: Mannan-degrading enzymes have been growing interest in bio-industrial applications, such as the pulp and paper, food, and pharmaceutical industries. In this study, an extremely alkaline mannanase (MnB31) is produced by Bacillus subtilis subsp. inaquosorum CSB31. MnB31 is purified to 17.92-fold with a 21.51% yield and specific activity of 1,796.13 U mg by anion-exchange and gel filtration column chromatography. The biochemical characterization of MnB31 is performed, and the results are as follows: molecular wei… Show more

“…An extremely alkaline mannanase (MnB31) from B. subtilis subsp. inaquosorum CSB31 was found to have the highest optimal pH of 12.5 and to be stable at pH range from 5.8 to 12.5, which was the most alkaline β-mannanase reported to date [ 53 ]. In addition, almost all the reported Bacillus β-mannanases displayed optimal pH at the range from 6.0 to 12.5 (Table 2 ), which indicated that Bacillus strains were the main sources of neutral and alkaline β-mannanases.…”
