Abstract: The quest for new cost-effective carbon and nitrogen sources from cellulosic raw materials such as agricultural residues of no food value to produce bacterial cellulose (BC) in high yield is a key challenge to cut down the cost of expensive ВС. We have developed a production technology for BC from oat hulls, involving four basic unit operations: (1) chemical pretreatment; (2) enzymatic saccharification; (3) mixed-culture fermentation; (4) ВС purification. The BC yield was 10% of the reducing sugar concentration on a dry matter basis. The BC was purified sequentially with 2 wt% NaOH solution, water, dilute HCl (рН 3) solution, and water again. An optimistic yield of BC was obtained: 0,95 ton of 98% wet product per 1 metric ton of oats hulls. In this case, BC features a high quality: 90% crystallinity index and 100 % Iα-phase, suggesting a superior quality of the resultant BC and successful engineering solutions at each technological stage of the BC production from oat hulls.
