Production of Cellulose from D-Mannitol by Acetobacter xylinum KU-1

Abstract

We found that Acetobacter xylinum KU-1 produced cellulose from D-mannitol. The optimum culture conditions for cellulose production were 1.5% D-mannitol, 0.5% Polypeptone, 2.0% yeast extract, pH 5, 30°C, and 48h. The amount of cellulose from D-mannitol was more than 3 times as much as that from D-glucose under the same culture conditions [productivity (mg/ml-medium) : from D-mannitol, 4.6 ; from D-glucose, 1. 2].
