Production of Bacterial Cellulose by Acetobacter xylinum through Utilizing Acetic Acid Hydrolysate of Bagasse as Low-cost Carbon Source. Zheng Cheng, a,b Rendang Yang, a,b, * and Xiao Liu a,b. Bacterial cellulose (BC) is a promising and renewable nanomaterial due to its unique structural features and appealing properties. Isolation and Characterization of an Acetobacter Strain ... Acetobacter is a gram negative, obligate aerobe coccus or rod shaped bacterium with the size of 0.6-0.8 X 1.0 - 4.0 μm, nonmotile or motile with peritrichous flagella, catalase positive and oxidase negative biochemically. Some strains are overoxidizer that could convert acetic acid to carbon dioxide and water. Factors affecting Production of Cellulose at the Air ... SUMMARY: The cells in a developing culture of Acetobacter xylinum in a static liquid glucose medium were swept to the surface by the flotation of a submerged cellulose net. The net was probably pulled to the surface by adsorbed carbon dioxide given off by the metabolizing cells. The relatively high oxygen pressure at the aerated surface of a static liquid culture mediated the rapid production Acetobacter sicerae sp. nov., isolated from cider and ...

Five acetic acid bacteria isolates, awK9_3, awK9_4 ( = LMG 27543), awK9_5 ( = LMG 28092), awK9_6 and awK9_9, obtained during a study of micro-organisms present in traditionally produced kefir, were grouped on the basis of their MALDI-TOF MS profile with LMG 1530 and LMG 1531T, two strains currently classified as members of the genus Acetobacter . Alternative Environmental for Cellulose Produced by ... Acetobacter xylinum is a gram-negative, aerobic bacte-rium that secretes cellulose fibrils as part of its normal metabolic activity (for a review, see reference 6). The substrate for cellulose synthesis is glucose, which is the major constituent of the medium in which A. xylinum is cultivated. Characteristics of Bacterial Cellulose Dariusz Danielewicz ...
