Bacterial cellulose is used in different areas. One of these areas is using this material as bioadsorbent for decolorization of different dyes. In the study, Gluconacetobacter xylinus was used for obtaining bacterial cellulose (BC). The wet and dry forms of the BC were utilized as bioadsorbent for removal of the Reactive Blue 171 (C.I Chrocion Blue HERD) (200 mg/L), Remazol Brilliant Blue R (150 mg/L) (C. I Reactive Blue 19), and Chrocion Green H-E4BD (100 mg/L) dyes. The highest decolorization rates were obtained with wet BC at the first use as 51%, 52% and 54% for CBHERD, RBBR, and CH GREEN dyes after 24 hours of incubation at 30°C, 150 rpm, respectively. These values were 11%, 21%, and 20% for dry forms of BC at the end of the first use. At the same time, the structure and morphology of bacterial cellulose were determined by SEM, XRD, and FTIR analysis. [ABSTRACT FROM AUTHOR]
