Production of a high activity of an extremely thermostable β-mannanase by the thermophilic eubacterium Rhodothermus marinus, grown on locust bean gum


The production of a highly thermostable mannanase by Rhodothermus marinus was increased 16.5-fold by optimising the concentrations of locust bean gum and yeast extract using central composite designs. The optimised medium and culture conditions yielded mannanase activity at 495 nkat ml−1 (248 nkat mg−1 protein). In addition, α-L-arabinofuranosidase… (More)
