Gluconacetobacter sacchari: An efficient bacterial cellulose cell-factory

The production of bacterial cellulose (BC) membranes by Gluconacetobacter saccbari, in Hestrin and Schramm (HS) based media containing glucose, sucrose, fructose, mannitol or glycerol as carbon sources, was studied for the first time. The highest BC production (2.7 g/L in 96 h) was obtained using glucose. The yields obtained are comparable with those obtained with other cellulose producing bacteria, and BC ultrastructure of the material was entirely similar. These results demonstrate the high potential of G. sacchari as a BC producing strain. (C) 2011 Elsevier Ltd. All rights reserved.FCTPOPH/FSESFRH/BPD/63250/200
