Selection and optimization of cultivation conditions for bacterial cellulose producer

The aim of this study was to increase productivity Komagataeibacter xylinus C3 strain on nutrient media using industrial wastes as carbon source. By-product sugar production, molasses, selected for the cultivation bacterial cellulose (BC) producer. It has been shown that significant accumulation BC (11.9 g/L) occurs molasses medium with 7 days in static conditions, which is 1.6 times higher than modified Hestrin and Schramm (MHS) medium. synthesized high mechanical properties (tensile strength – 38.34 MPa relative elongation at break 3.34%). replacement source MHS production did not alter polymer structure its microfibrillar nature affected by composition introduction promoted a cost decrease culture almost 2.8 relating cost.
